Sorry if this is already a suggestion, I didn't see it when I searched keywords. ^^'

If at all possible, Clan Messages should show up in your inbox, not in Game Notifications. I know I personally lose quiet a few clan messages and don't see them until days later because I don't get a message alert for game notifications like I do for inbox messages.

Also, I think it'd be pretty nifty if in the Clan hubs there'd be an option to personalize a message to those you accept AND reject.

It'd be it's own little box, and you can put all the info you need for each message respectively. You would then hit 'save,' and when you accept/reject a player, they would receive the appropriate message.

I feel like the reject message is too impersonal, and it can potentially cause passive aggressiveness when players don't know why they were rejected.

Suggestions
Zelda suggested keeping the clan messages in notifications, but getting a special notification just for clan messages.
-Possibly fixing the notification system to include it's own pop up for game notifications that's consistent.
