Well, we.............almost have foundry in tribble.
You can sign up to review UGC missions
You can check out a UGC mission...if they were any
You can go to create UGC at the character choice menu at the start...it is a tab at the top
and and and, all you need is an open slot to make a test character, so that you have a toon
to run though and check your work
Do you see any of the missions made during closed beta? You probably need to know what to search for, and I'm not sure if I'm allowed to say the names of the missions that are on the foundry in closed beta.
