deviantART Username Changes...are now [allowed].
It requires premium membership
You can only change your username every six months
All links to your old name will redirect to the new one
Old names cannot be retaken by anyone (including yourself! Once you change it is for good)
Though people who want to be taken seriously on dA (yet called themselves "lololBUTTS") will rejoice, I have concerns.... for one reason, it makes you very hard to find if people are still referring to you by your old name. For another, it will confuse the hell out of your watchers - and if they don't know who you are, they may remove you in their next +watch purge. And three... I worry people will feel less pressure to actually THINK ABOUT what they are calling themselves, because they can always change it.
That and I worry they will change it for silly reasons.
These are the only reasons
