mattblaze, 
Periodic reminder that the "Direct Message" / "Private Mention" function here is dangerously broken with confusing semantics.
Anyone mentioned anywhere in the body of a PM gets a copy.
"Disabling" PMs in your profile merely means YOU never see messages sent to you; senders can still send them, with no error indication.
Nothing is encrypted, which means administrators on any instance that processes a message can see them.
I strongly recommend using something else for private messages.
