yay! V2 is finally here! I know there is a new collab feature from what I've seen, but how do I use that feature? If anyone could help me here it would be appreciated!

If you are the one starting the picture, You just press the link at the bottom of the submission page. Then I think you type in the usernames of the people you want to collab with...O__o I've never hosted one before, so I'm not sure.

Somewhat like that n__n; Roy's got the first part right..
After you submit a drawing, there is the word 'collaboration' at the bottom, click it and then select the users you want in your Collab. (Select, type in name or user number. Ok'ed) etc.

Ok. Thanks for your help!
