Is the whole rest of this site down except for the forums?

Yep. Been this way since late last year.

Intentionally or just needs fixed?

I haven't been on here in months due to the login failure. It wasn't until yesterday when I was looking for a post about windshield wipers that I was able to see the forums. And I came directly to them, bypassing the main page. When it was down for 3 months, I tried to find the owner and buy the domain, but had no luck tracking them down.
