Hey all, Larry just confirmed that he's working on a way to let users modify some aspects of the look/feel of the site. It will probably be limited to some basic color changes, but we're not going all MySpace on the site.
How we unlock that for you is yet to be determined.
I think this would be a great thing to implement in the new AG3 version! This way more people will be attracted/persuaded to stay with AG, since the option to change their profiles is something users really like to do in MySpace! =)
But keeping it simple is the best thing to do here, so I definitely agree on not making it to extensive... that would only cause massive use of the 'Hide Personalized Profile Button'!
