What i know i found irretating about the forums at first was that it was rather hard to get a grip on how to find folders and how to add them to the forum sneak peek.
Geez, you can do that??? Wow ... how?
Then if you want to remove them as you become more acquainted with how the forums work thats fine by me.
Also make it so that there are 10 threads in each folder or so that you can choose haw many you want to see at the sneak peek.
And you can do those things, too??? Wow. Now is there somewhere where they tell you how to do these things? That would make the forums better already!
