Duplicate, mail remove (?)
 

Hello,

I hope that this is the right section to ask my question.
Its about the following issue. Id like to have a check at duplicate registerd mail addresses in my admincp. And that by the check i can remove the duplicated (lets say the oldest members stay the new one have to register a new mail address.

Is this modification already available? And if it is - please give me a link to it.

Thank you,
Mr_Virtual

Check this setting:

Admin CP > vBulletin Options > User Registration Options > Require Unique Email Addresses

If this setting is "yes", no users can register with the same email address as another (existing) user. If you have had this setting as "yes" since the opening of your board, there is no need to find people with duplicate email addresses.
