Try this way: click on "Manage Account" and then click "Edit" in "Account" section (under your profile photo). I don't know whether it works because I didn't try :P

Damn, I did it before, and I think that's how... but I'm sorry I can't say I remember... try that, and of course check your email afterward. That much I remember... oh maybe when you first signed up it may have a link to request password change or something... but try the other way first.
Sorry I couldn't be any more help

They must just LOVE fans like me.... and then hate them later when they actually show up to their shows…
