I'd like this or a list of threads you have recently posted on. Because then even if you weren't quite as interested in the thread you could still go check out what you've done lately.

For that one, if possible, I think it would be nice if it could be displayed for other users as well. Maybe a bit stalkerish, but knowing when a friend has recently started up a topic without them pinging you or looking all through the forums would be nice.

But just the favourite threads would be nice too, I know I lose them a lot.
