Once this article reaches the front page, it means this new forum is live and the old forum is relegated to archival status. It'll exist, but everything feeds from and points to the new forum.
If you're curious, the new forum software is called SMF (Simple Machine Forum). I'm switching to it because the old software (e-Blah) had to be locked down because it couldn't handle the spammers. SMF supports modern anti-spam technologies including Google's reCaptcha which you would've encountered while signing up.
