Yep I disabled (and visitor messages) it temporarily.
I noticed that PMs would not send when the recipient was chosen from the Friends list. I removed the friends and foes function to ensure members didn't needlessly write large PM's which unbeknownst to them never reached their intended recipient.
It's part of the testing to get PM's working correctly, I've been changing random things in hopes that'll we'll uncover the hiccup that is preventing PM's from working for select people.
