Seems to be working for me for default forums. Getting both emails and PMs. Great job!
Now my problem, I have several forums that use Abe's Forum's Hack and this does not seem to pick up the keywords when a thread is submitted via a form based forum. I understand that it is "not your problem" 100% but perhaps you could have a look at his code or maybe he could look at yours in order to get these to function together? I will not be able to use this without that functionality. I will make a post in his
forms hack thread as well.
