Can my less than 3 character username be grandfathered in when I edit my profile?
I just logged into my account on stackoverflow and tried to update the website link. I changed this one entry (and nothing else) and when I clicked "Save Profile" I was told:
Oops! There was a problem updating your profile:
Display Name must be at least three characters
I would understand this being a problem if it had been the case when I originally signed up, but I don't understand why I need to change my display name from 'Al' (which it has been since I signed up) just because I want to update the website address.
Is there anything I can do about this?
