I thought of the msg as like "it's too busy right now" kinda thing, so after repeated attempts I tried another, guess i'm stuck like this for 6 months unless @OneLetter or @KThxBaiNao changes it, I don't even want to use this forum if I have "Keyan222" as my name, I fear someone is going to impersonate me too.TheyYou couldn't know. I guess it's the case of the abbreviated update notes, all over again.reallyneed to be more informative, I read FAQ, TOS, pretty much anything I could find and found nothing about this, i'm practically new to this new forum, how am I supposed to know?
That post from @OneLetter, that I quoted, was in response to someone with a similar problem to yours, who posted in the first day in the Tech Support forum. I just happened to see it.
I agree this sort of thing should be in the "Welcome to the New Forums" opening post, since lots of people want to change their names. The fact that the error message is "can't do it at this time" and not "name is taken" only contributes to the confusion.
