I should imagine some threads are re-occurring e.g Birthday, Confession, Compliment, user name origin etc. To improve the forum why don't they pin some threads at the top of the forum outside of any section. These are three good threads that could be pinned, plus a couple others, outside of the sections.
Also they should have a section for new posters to introduce themselves., .if they don't already have one and I've missed it.
Sorry if some of these have been suggested in the past.

Threads are pinned at a moderator's discretion. I usually pin something if I consider it to be important information for the community or if it's a particularly good thread.

But mostly, pinning topics just wastes valuable screen space for most people so we usually keep them to a minimum. The suggestion for an introductions forum has already been made several times, and Toby is working on it, thanks though!
