Here's a few to get you started....
Just click on the "community" button above. There you will find social groups (let me know if there's some categories you want added), pictures and albums (note this is separate from the gallery), contacts and friends (much better than before).
Also, if you go to your control panel, you'll see that you have a more customizable page (got to mine as an example:
http://www.clubcobra.com/forums/member.php?u=9454 ).
Have fun!
