Okay, I will now boldly stand out and argue with my little idea.
Right, I know that there have been these users here and there that asked if they could change their names. The answer has always been 'No'. Fine, I'm alright with that. Now I was thinking about something like a nickname. It is always changeable and will be on your Profile. Then people will know what name you prefer to be called and use it. I know it sounds like a waste of time, but how about it?
I am not sure about this idea. Before they make an account, they should be sure if they like their account name. If not, can't argue with that. I have nothing against the Nickname idea, but I don't think it will do much good. Just my opinion. My nickname would be Zega and there aren't many people who wants their username changed either.
