changing of the user profile

hi tbs people,
every time i try to edit my profile, after a ‘change profile’ click, i get a message:
'That email address () is being used by a registered member already. If you feel this is a mistake, go to the login page and use the password reminder with that address.'
i am logged in and try at the edit profile interface.
is it a bug or a feature? :wink:
thanx in advance

I don’t what might be the problem.

I asked the webmaster to look into this.

Thanks for reporting this problem,
