But why did you change your username is the real question here.

@Matse007 the reason is that I like Torchic more than Pikachu now. Not a special reason.

Don't wanna be that guy, but you should really stick to one username in the internet (unless you want to vanish from the internet or "restart" but that would mean never touching old accounts and creating new accounts for everything). A nickname is like your identity on the internet and changing that is going to be very confusing. I would have never known that you are pikasriel from seeing your name pop up here on the forums.

Also your credibility and reputation is bound to a username. Not everyone will read this forum post and will be probably assuming you are random new user #2312315124

@Matse007 most of the time a community associated to a runner will know who you are, but I agree that you shouldn't change your username often. To each their own tho :p
