Rusty, could it be something in the firewall or your ISP?
I started out thinking it might be my firewall. I have three computers, running two different firewalls. None can access the site.
I then thought it might be my router. I checked it last night and nothing is blocked.
I don't know about the ISP, but have no idea how to check or what it would be.
What leads me to believe that I'm blocked someplace is that I'm on a couple of sites that ban access for troublesome posters. They do this by blocking their IP. Some of these posters will use an anonomyzer to circumvent the ban. I accessed an anonomyzer to test it and found I suddenly have access - through the anonomyzer. I've had several e-mails with Atash discussing the problem, and he's never mentioned that I got banned, so I'm guessing I didn't.

I'll be the first to admit that I'm not really a computer person. I get on them and kind of expect them to work. Solving tech problems is usually hit or miss for me.
