Well, considering there was no voice acting forum until two weeks ago I'd say it's still pretty new! ;) Official announcement was here: http://www.newgrounds.com/bbs/topic/1379622
Or... maybe you meant the New before Grounds?
Anyway, it's fun to hear the forum might be a the decisive feature in luring in some users! Didn't really realize the voice acting community was so large until the forum popped up, and what a response! Btw, though you just got here, there is a collab going down right now that you might be interested in. Voices of NG: http://www.newgrounds.com/bbs/topic/1377563/1

Hey there Real Sketchy Character! ;) Wonder if the new voice acting forum was what inspired you to join? There's always plenty of demand for good voices, hope you find some inspiring projects to work with!

Actually, the new forum is what coaxed me to finally join. I'd been toying with the idea for a while, but it wasn't until I'd conversed with a friend on Facebook about NG, that I finally decided to make the decision. (I know it isn't "new" per se` but it is new to me! Since I didn't know about it until a week or two ago.)
