Forum search & thumbnail generation
The forum can become quite busy and should have a quick textual search option. There should also be an option to collapse/expand all comments.
It would also be nice if the forum would instead generate *thumbnails* (cached or on the fly generation) for the images uploaded instead of downloading full size images. (Although they show up as thumbnail size, the forum is still actually downloading the original image each time. It should instead use GD to generate a thumbnail.
