Hi:
As the admin my username on a forum (VB 3.8.1) I run is "ddadmin". I just noticed a new member with the exact same username sign up 2 weeks ago, and successfully so. Doing a search for the user "ddadmin" inside the control panel also returns both users. I thought vBulletin disallows registration using the same username more than once. Are there any known security bugs in the version of VB I run (3.8.1) that may explain why a user is able to sign up using the same username as an existing member, in this case, the admin actually?
