Although I am content with my current username, from time on other communities, I would certainly be willing to pay a small cost for a username change. Especially if it goes towards a better server which could handle them more easily.
If all proceeds go towards the PokéCommunity funding then I don't see why there would be an age limit in all honesty. I'm sure many usernames are chosen as a spur-of-the-moment thing anyway so I think it's completely understandable that a very new user would want a name change, although I expect that such a user would make an alt account instead of paying for a new name.
Just one question though for if this actually does get through. Is there going to be some sort of account age limit for this? I mean sure it might sound discriminatory to those newer people, but for those who say, created an account a couple of days ago and want a name change, something like that wouldn't be allowed?
