Testing if I can post on the new forum
+1 for screen-wide forum. The main website content shows as tiny column on the middle of the page, even on my almost-Full-HD resolution monitor.
This is a theme thing, it looks nice on the pages that are blog-like, but it doesn't look very nice or usable on the forum.
Plus, why "require math" when registered users are posting? I think the fact of being registered is enough to tell if it's a spammer or not.
