For 7.5, something that could be made that wouldn't get lost later on is a PM permission overhaul.

You already added the max topic size. At my board I hacked that in, and also a max. topic age. If the PT is 3 months old, you cannot reply in it anymore.

Next thing on my to-do is to not allow replies in topics where it's just you in the topic.

To keep things current, and not to be an archive, the next step after that would be to turn of sending PM's for anyone that has PT's that haven't gotten a reply in a year to force them to clean up.

Also my earlier request to impose limits to the actual owner of the PM box, instead of the people sending to that BOX would make any limit scheme a lot easier to code and maintain in the future.

And another small feature request, the e-mail PM could be enhanced. Include the subject, and also make the function available from within the PM. It's nice when you are reading the actual PM to be able to "delete/mail it" it on the spot.
