Delete Guest posts
 

I need to delete the Guest posts.
I saw in the forum you suggest to run a query (http://www.vbulletin.com/forum/showthread.php?t=132219 ), but I don't know where exactly I have to run it. What do you mean by: "Try running these queries on your database (backup first):" ?
I mean, how do I reach my database, in order to write the query ? Is it outside the Admin Control Panel?
Is there any easier way for the Admin to delete a spammer's posts qualified as a guest (because I delete the user and he was converted in a guest)?
thanks
