So personally I really like the idea of clans and I just wanted to post a few suggestions for possible expansions in the future c: If you have any other suggestions or critiques please post here and I will add them into the main post w/ credit as applicable.

Clan Forum:
Just a small private forum where clan members can post and chat amongst themselves. Possibly make a limit depending on the clan size (example: If you have 40 member slots purchased, your forum will only allow 80 posts or something along those lines) and give Admins availability to Delete, Edit, Sticky posts to that particular forum.

OR if giving members free range to post what they will is too much of a liability, then maybe make it so only Clan Admins can post main topics where members are able to respond too. Benefits to this would be creating Topics such as: Clan Rules, Member Introductions, Member Sales, Clan Exclusive Raffles, Etc. If this method is chosen then the number of allowed posts will obviously change (for example: The initial 10 slots gives you 5 topics, each additional 10 slots after will allot you +3 topics which comes out to a max of 39 total topics at max 100 members slots)

Invites/Invitation Only:
All clans are going to have different goals or requirements. So a feature where you can send invites to members you feel would fit well into your clan ideology could be very helpful.

So say a Clan Admin finds a player they want to invite into their clan, they can send a message that stats "[INSERT CLAN NAME] has sent you an invite to join their clan!" They then click the clan name (which is obviously linked to the clan page) and they are given an "Accept/Reject" button. If they accept, they are automatically added to the member list, if they reject they are removed from the pending approval list. Of course you would be limited by how many available members slots you have (so if you are at 23/30, then you can only have 7 active invites at a time).

Now you might be asking "that seems excessive, why don't you just send them a message asking them to join?" Well that's because if invites are implemented, then I would follow up by suggesting an "invitation only" option for clans. Pretty self explanatory really. Non-clan members can see the clan's main page, but will not be able to submit a membership request, or maybe even make the entire clan private where if a non-clan member tries to click the banner they are simply given a "You must be a member of this Clan to view this page!". I think this would help with people getting upset after being rejected from a clan because the clan admins did not feel they were a good fit.

Block Members:
Maybe you reject a player application or boot a member, and they get a little bit more upset than they should about it and start spamming membership requests or targeting clan members through the membership page. A Block feature would basically block that player from accessing that clan's information.

Clan Bank:
Clan Bank for member donated funds to help with clan activities. Deposit/Withdraw activity will be made public to clan members only so everyone can see what funds are coming or going.

Donating: You can donate any amount of SB or GB and will be given a notice similar to transfers: "Are you SURE you wish to send these funds? All transfers are considered donations and are given without the guarantee of receiving anything in return." or something. You will also be given an option to donate anonymously and include a short message with your donation. For example, say the donation is driven by a clan raffle. You submit the funds and leave a message "3 tickets for the Member Raffle!"

Withdraw: Only Clan Admins will have the ability to withdraw funds. With each withdraw you are given a text space where you can put a small description of why you are withdrawing that amount. For Example, you pull out 300 SB and a message is listed beside it as "1st Place Raffle Prize". This will give the clan members more insight of what is going on with clan funds vs. sweating over why the bank total just tanked by 3k.

SUGGESTION:
KammeKeys [Lights On!] (#57143) - Maybe, for Clan Renewal Fees, you can set it up so there is an option to pay it from funds straight out of the bank?

Clan Branch:
A Branch that is only accessible to Clan members. Possible features could include a Minimum purchase amount designated by Clan Admins. For example, setting it so members can only purchase something out of the shop every 24 hours/2 days/1 week/etc. Funds from these sales will go into the Clan Branch.

Clan "Modbox" *name needs work*
So something similar to the Modbox but at a clan level :P Members can post suggestions or complaints here that only Admins can see. Essentially the idea behind it is that the first available admin can see the issue to handle it or discussion can begin between admins vs:
-Someone sending it to all the Clan Admins through personal message and then Admin A deals with the problem just for Admin B to come on board and also try to handle the problem.
-Admin A assuming Admin B is handling it while Admin B believe Admin A is dealing with it.
-the message getting buried int he mountain of other messages they have in their inbox ETC.

SUGGESTION:
Name suggestion by KammeKeys [Lights On!] (#57143): Admin Message Box

*NEW* Clan Affiliates/Allies:
Just a list available in the main page of other Clan Affiliates/Allies. Requests will obviously only be available between the Clan Owners. I would also suggest there being a limited number of Affiliates/Allies one clan can have, but not sure if it should be based on Clan Member slots owned or just a a set number across the board.

*NEW*Clan Tabs inspired by WhiteRabbitAkira (#65156) and ~Cyll~ (#34465)
Allow clans to have separate tabs on their main Clan Page. Here they can better organize information for their clanmates. Maybe have one tab that list current member trades/deals, and another for an ongoing raffle or contests, etc.

WhiteRabbit's original concept was about having tabs to store lions that were being held for contests (I believe I understood that right?) but I feel like that could be too easily abused since it could be used as additional storage to free up space in a members main den. But after reading Cyll's suggestion that there be a designated place for clan links vs. only the Main Forum Thread link, I felt that the Tabs could be incorporated into more of a clan organization concept than storage.

*NEW* ~Cyll~ (#34465)'s Corner
-Cyll thinks we should be able to have more than 100 members in a clan. U LONLEY CYLL!?
-Cyll wants the ability to preview clan pages before editing. CAUTIOUS MUCH CYLL??
-Idea 3 Placeholder. CYLL'S KICKIN' ASS!
-Idea 4 Placeholder. CYLL'S GOT HER SHIT TOGETHER!
-Idea 5 Placeholder. CYLL FOR NEW WORLD ORDER!

That's all I have at the moment, interested to gain y'alls input on this <333
