PM Email Not Sent Mystery Solved

The mystery of email not being sent receiving a PM is solved. Now you will receive email notification when somebody PMs you.

The problem was that, in tge Admin page, I turned off "notification when post is replied" to reduced the annoying flood of emails to the users. Unfortunately, that "reply" includes PM, doh... Bad design of JForum.

So, you now will need to turn it off yourself in your own personal preference.
