Let's see:
-Staff overhaul
-Derek and Nikki are gone
-New Supermods are Craizen, Keylade, stormform, and CrypticWizard
-Me and sphynxx are new admins
-Crossy's still here, as ever
-All of the general boards were consolidated into general chat, besides FF&RP, S&P, and new members.
-We've got the new Wikis section for people to contribute on
-Rich is taking an active roll in the community now, we're all bouncing around ideas on how to better integrate video games with the forums, ways to boost activity, doing something with Teams. Just general updates and stuff.
I think that's pretty much it. Reading through the New Staff Line-up thread may help more.
