Hi daggerman99 -
The forum is a software called vBulletin - it is written in a language called PHP, and uses html and style sheets, with a MySQL database to store the thread text, user info, authorizations etc.
The owner of the forum, or the Admin, controls what privileges that the users, moderators, supermoderators and co-admins have.
In the case of bladeforums, they have in place a graduated schedule of privileges based on a heirarchy tied to your level of paid membership. You pay more to get more privileges.
However, in the case of your inquiry, i.e. removing threads, that is a function normally only granted to supermods and higher.
That makes it important to the casual user to think about what they post, and only post information that should be scribed into stone for the ages.
best regards -
