If you want to pay, there is always the National Association of Photoshop Professionals (NAPP). They have forums there. I'm not a member, but that would cover your interest in a photoshop forum. http://www.photoshopuser.com/
Google search is your best friend I am sure there are TON of Adobe forums to your taste.

I got tired of playing around with Adobe. I couldn't download.
I ended up downloading Foxit PDF Reader. I'm happy now.
Ooh! Can I join the <adobehatingbandwagon>?
Just in case uberman isn't uber enough to type adobe.com into his browser, this should help. (It's the very first result.)
ADOBE'S own website!

I mentioned them, but you're a member of more than one tech forum, right?
