Having a search function for the forum would be nice. Or, at the very least, the ability to see recent posts that you or someone else has made via your/their profile. To keep clutter to a minimum, perhaps only the last ten threads posted in would show up in this list of recent posts.

I have lost track of a couple different threads now and can't find them no matter where I look. I know who made one of the posts, but that doesn't help to locate it without any sort of search function, thus the idea for this.

Gosh, I need this.

Seconding this, my memory's horrible and trying to keep track of threads I want to follow is a real chore especially if I don't even remember the title of them.
Wish there was some sort of subscription function too on that note so I could get alerted on replies to a thread without needing people to constantly ping me.
