You
can use the dev thread tag, but (unless I'm mistaken) a development thread can be in near;y any thread, private, public, skirmish, etc; as long as at least X amount of posts focus on whatever item you're developing. FOr instance, if you want to create (and i'm just naming something random) a sithspawn carebear that requires 50 posts, you can do that if you'd like right in the middle of a battlefield. I=You would probably be shot while concentrating, but you get my point. And yep, you can have as many people help you out as you'd like!
TL;DR: No, you do not need a special tag. Yes, you can have friends help.
