vBulletin Manual - Search Results

The search results page will display the users who match your search criteria. The columns that are displayed depend on what you chose on the advanced search screen. By default, user name, email, join date, last visit, and post count are displayed. In addition, the Options column contains links to manage a user. These links include:

View / Edit User – displays this user’s information. See the Adding or Editing a User section for more information.
Send Password to User – redirects you to the lost password form, allowing you to send a new password to this user.
Edit Access Masks – allows you to edit this user’s access masks. See the Editing Access Masks section above for more information.
Delete User – removes this user from the database. You will be asked what you want to do with his or her posts.
