I mentioned this in my comment about moving but I was wondering if it would be okay to employ Appointment Posts as an official, but optional, thing? Since we're moving into a community base system it can end up being useful to those who want to thread something simple, but don't see the need to make an entirely new post or log.

Basically it would just be a simple post saying if someone wants to thread with that character, they can start up a thread with permission from the other person. A few people mentioned that the journal element felt important to them, so this can be a reasonable addition. I have an LJ example here from another game and I think it can be a cool thing to have, since Mayfield has a lot of day-to-day things that people may want to thread with their characters.
