Help me out here Mods

After lurking for months and not being able to post in the other threads, I found out this morning I can post only in the Introductions (and this) thread...what do I have to do to get unlocked in the others? i can contribute some reviews. Lastly, can I change my username? Thanks!

Been a bad boy already? Lol. PM the mods may get a faster response.
