How do you edit your profile?

at the bottom of the page you'll see a column titled my account, select my profile from the list, from there you can add an avatar using gravatar.com (must sign up using the e-mail address associated with your A2K account), add profile information, ad a signature quote to your posts (text only no images), add your location, occupation, you can also link a Last.fm, flickr and youtube account

Thanks!
