If there is a PM with, say 3 or 4 participants, is there a way to completely remove the topic once ALL participants have removed themselves? It seems (I could be wrong) that when you remove yourself from a PM, there is an entry in the database saying so. What I was hoping is there might be a script someone has that you can run so that if a topic has NO more participants, that topic and all references to it can be deleted from the database.
