Firstly, Why did they call it Psychipper? I like the name PsyKeeper better :(
Secondly, How do you change your password?

On the FlyFF Forums it's called Psykeeper:

I think you can't change your pass, unless you say that you forgot your password and want a new one, then you get mailed a new pass.

so the only way to change a pass is to msg the GM?

I guess so, but beware, I don't know for sure. :) There's no 'account' button on the site or so..

im sure if you emailed them and said that youve been missing some items and think someone has hcked your account then maybe you can get a new one. i might give this a try also
