Petition Poll for username change

[Angrboda]

The impetus for the original rule was that people changing usernames was confusing to people. Since then, the 'previous username' tag in the info next to the person's avatar has been implemented, rendering the initial rationale for limiting changes moot. Since the rule no longer serves any real purpose, retaining the limit just because of tradition, that that's the way it has been, is stupid. I think a reasonable limit might be arguable, but restricting it to a year just seems to punish those who might want to change it sooner for no reason or benefit.
