Basically, go to "User CP" in the upper left hand corner of your screen, and change your options. I'll go through "Settings and Options" with you all:
Edit Signature- [ img] can now be used, unlike when the board first opened.
Edit Email/password- You probaby had to reset your password to get in, so please change your password now.
Edit Profile- Just about everything was transferred, so you shouldn't have to do much here.
Edit Options- Please change your time zone, and most importantly, the very last option: "Message Editor Interface." Unless you want to type your posts in nothing but a blank "quick-reply" box with no advanced features such as color and whatnot, I suggest that you change it to "Enhanced Interface.
Edit Avatar- Avatars can be used, as of the 23rd.
Edit Profile Picture- Sure, why not?
That's all the basics you'll need.
