What I do, is I copy the person's username and paste it into your freinds tab on your profile and click the "+". Hope this helps!!
Hi, again! Sorry it took me so long to reply to this... But anyway, to answer your question, to collab, follow these steps... 1. Ask someone to collab (duh... :v) 2. If they say yes, make a coversation in forums. 3. Invite the people who you are collaborating with! To do this, when you create a conversation, type in the participents in the "Participents" bar. 4. When you do your part of the collab, give the collaborator(s) the track code. 5. When everyone is done, you did it! Decide who's going to publish it, and you are done! Hope this helps!
