mariz_p on "add user notification in bbpress moderation"

I have modified the bbpress moderation plugin since I'm not getting any response from it's author.
Please see this link: http://pastebin.com/EMmZK1Zt
for my code.

Now, my problem is I cannot make it work. I have checked the structure of wp mail and I know I'm in the right path. It's just why it's still not working.

I hope someone here can help me as I've been struggling on this for months now.

Thanks and have a great day ahead.

Best regards,
Mariz
