Not sure if this has been suggested before, my bad if it has!

I believe this would be a lot easier for people who run art sales threads with multiple people, adoptables with multiple people (such as me n' my friends Commie / Greeky / Peach), n' especially clan threads and what not!

This would not be a requirement for anyone to have collective authors on their thread, but more a small box you could tick that says possibly "Add multiple authors/editors", and then from a list of your friends you could search who do select and add on perhaps?

Let me know what you think :o !

Addition 1: Thought it'd be a good thing to add:
This would only allow the added authors to edit the thread, add on HTML things, etc! Do basically anything that you can do with a forum thread and what not while editing. HOWEVER, only the original author and owner of the thread could DELETE the forum post itself! So no worries about someone accidentally deleting it<3

Addition 2: The owner of the thread could add and remove Co-authors at any time! The only limitation I'd see is around 10 people per thread to work on, any more and I feel it would be cluttered and difficult to work with :(
(Plus, I'm not sure who's gonna work with 10+ people on a thread anyway--)
