We ran into some issues with our host. Apparently we are using too much CPU at certain times. I am pretty sure this is due to us getting hit by Yahoo, Google, and other such bots.
I have made a change so that all the forums are private, and you must log in to view the threads. With the exception of the Announcements forum.
To any guests that have not registered, you will no longer be able to view any posts w/o registering. Registering is free and only takes a minute. If you do not receive your activation email, make sure to check your spam filter for an email from firstname.lastname@example.org.
Sorry for any inconvenience, hopefully this will help the site perform better on our server.
