Some of you may have noticed that this website has been updated recently. I've changed the layout, added some new sections, and most importantly added some spam filtering for the forum (I cleaned out over 20,000 pieces of spam).
Unfortunately, while I was doing this, I inadvertently screwed up the captcha settings, so it seems for the last couple weeks no one has been able to post comments or forum topics, or even create an account with which to do so. Sorry for the inconvenience - it's fixed now!
