Hey! Haha I'm kind of a computer nerd If you go to the upper right corner you'll notice USER/CP - click on that and it takes you to a page where you can modify your avatar (what shows up when you post) and also where you can change your main photo that people see on your profile! You can also add to your ABOUT ME section and stuff
And thanks for the suggestion! I might have to add some creepy sound effects on a kind of hidden ipod dock or cd player, that's a great idea... thanks!
