Is there a Q&A site dedicated to graphics? I was using vfxoverflow.com but it seems dead.
I mainly want to ask questions about photoshop, fireworks, etc.
You might get an answer on Super User. It's not all hardware and operating system questions on there.
Another alternative is the Graphic Design site, but that's still in beta so you'd need to a) get a moderator to migrate the question for you and b) have a question that was a very good fit for the site.
