A couple years ago i made a second account with the email I
currently use. warnings were already received and that fault has
already been dealt with and that account is locked. however, I want
the email for that account removed so that I may use it on this
account since the email for this account is one I never use.
There's a section for e-mail settings on the profile
settings page where you can change your e-mail address.
In case you've already tried that and the issue is that it won't
change it due to that e-mail already being linked to a different
(locked) account, your only hope is probably contacting Riako about
it.
