Just wondering if you allow your site's users to change their nicknames?
As far I as know, Facebook/Twitter and most other social networking sites do not allow their users to change their nicknames once it has been set.
I've disallowed mine (removing the nickname field from admin> builders> field builder> edit profile>).
Just want to hear your thoughts about whether you have too?
*Or maybe is there a way to just allow the user to change their username once? or maybe once every six months?*
