A few days ago, I had my host change some things that caused me to temporarily loose my dedicated ip address. I did not realize at first that this change also blocked the SMTP port my site uses to send mail. Thus, registration activation emails were not sent. If you registered and did not receive an email, I've manually enabled your account. You will now be able to log in to both the site and the forum.
Hopefully my host will get things worked out very soon.
