No, you aren't crazy. The look of the site DID change, again. My hand was kind of forced, this time.
If you'll check out the tabs at the top of the page, you'll note that a Forum tab has been added. Now, to be honest, I'm posting this before even taking a look at the forum and seeing how it works. So if you see it vanish, or the site revert back to the previous layout, it means I was less than enthused with the addition. I'm hoping it will give people another means of communicating. Sometimes, comments just aren't effective for discussions.
So, stop by the forum and see what's up. I'll be playing with it to get the layout right. Feel free to start a discussion, make comments, ask your own question, or answer that of another person.
