Apologies for creating another topic for this but it appears I cannot post twice in a row. I had one more question about this. When I'm changing my username it says to enter security check; password. Does that mean that I enter my account password?

Yes, that's exactly what it means.

Yes it does. It's to make sure no one else can change your username. (You can edit your previous post if you want to add more to it instead of creating a new topic--for future reference).

Ah, okay. Thanks!

It's saying that my password doesn't match. I tried it several times very slowly to make sure I got it right but it's not working.

you'll need to change your password, then do it. it's a glitch, but that's the way it works. idgi.

Thank you, I'll try that. Hopefully you won't hear from me again XD
