Nothing terribly exciting to report; I just don't like having the last post on the front page be over a month old because it makes people wonder if I'm still working on it. I'm deliberately not putting this on Planet since it's a lame post. Hopefully no one is subscribed to my RSS directly; if so, I apologize for cluttering your feed.
Anyway, I'm still plugging away at it. The basic forum functionality works fairly well. You can do CRUD on forums, threads, and posts. Still no real theming, though. I'm saving adding the style system until I get the foundation solid. I'm also still making changes to the schema fairly often so it's not safe to use for real data. It's getting there, though. My goal is to have a basically usable forum by DrupalCon and then work on enhancing it from there.
