Can't find user

Someone tried to register on the forum but mis-typed the email address or something, and therefore the account never got activated properly.

The problem is that he can't log in to sort the problem, and can't register again with the same details because the account exists somewhere. When I search the member lists, his username isn't there because it hasn't been activated.

In other words, the forum is holding the account details and they can't be accessed or removed. Is there anyway I can find unactivated accounts so I can delete it and have him register again?

Users & groups>Inactive users
Check if the user is there & activate the user.

Thank you, don't know how I missed that lol
