Talked to Jonathan about this issue again.
We came to the decision that the old subject line (from the intro email) was too generic, and easy for spammer software to send off a authentic looking request.
So, we decided to change it to something that's really unique.
"K'Tesh Sent Me..."
Not that I personally sent everybody here to Jonathan, but you gotta admit, this is not as ordinary as:
"Please approve me for the forums"
Hopefully this will streamline the process for legitimate forum members.
