Thread:Extension talk:User Merge and Delete/Usernames with "@" character cannot be deleted or merged

Whenever I try to Merge & Delete a user with SOMETHING@SOMETHING I get the error message "Invalid old username". Any idea why this might be occurring? Is the @ symbol a special character that doesn't play well with this extension?

Thanks in advance --Stanimalz (talk) 12:39, 5 June 2012 (UTC)
