I'd like to change my username & password in DS/BR. Does anyone know how to do that?

[Report:]
I don't think you can change the username - but maybe someone whom deal with customer service before can answer this better.

For password, go to https://id.konami.net/login.do and switch country to Japan, language to Japanese. Log in, then edit info.
[End of report]

PS: Too lazy to post screen shots tonight, sorry...

Could you please post some screen shots when you're not feeling lazy? It'd help me out a lot.

I think i remember someone mailing Konami about a username change. They said no, iirc.
