Ok let's say there is a YTF forum (version 1.9.1.7 (NET v2.0) - 11/20/2007). Let's say on this forum Timmy sends a PM to Billy. Billy deletes the PM from timmy and Timmy deletes the messasge from his sent box. Is there any sort of log or database where the PM would still be recorded even though both parties deleted the message?

If so could this log/database be easily compromised by a regular user?

Keep in mind the version....if that is in any way important.

As I remember you can do nothing in the version, users can delete messages from other user pm boxes anyway.
