[quote author="enatom" date="1270417092"]Also, I don't think you should allow users to Change their username... becuase I'm trying to create something like this www.blah.com/username ... so their profiles are viewable, and that can't happen if they're able to keep changing it.[/quote]

ok i've strong reasons why we SHOULD allow your users to change their username.

1) it's good usability.

yahoo doesn't allow me to change my username and that's to me crap!
i'm stuck with the lame username i choose a decade ago... but i can't junk my account easily cuz i used it to sign up for so many other stuff. Bad usability.

2) Twitter allows us to change username even though it gives us a nice url (e.g. http://twitter.com/cHaOs_pk). They reason they allow it is because it isn't a problem to change username if you design the system correctly. You change username your URL changes. that's the control we give the user... which is the 3rd point.

2) Give users full control. protect them from screwing themselves over permanently but do it without taking away control.

basically imho 'it can still happen' even if you allow users to change their usernames.
