Thanks, Mike. You're really not missing a lot. I happen to hang there because a few guys I've gotten to know frequent the forums there. Several of them aren't really comfortable with AC- they think it's a bit to "expert" for them!

The site is run by some engineers who are ultra-objectivists. I like the reviews and they do a lot of them.
I did consider that maybe my router/firewall was blocking the new site, as I had no trouble whatsoever before they migrated to the new one. I haven't tried it yet, though. Like you say, I'm not keen on running with my ports wide open to any virus or worm that wants to wiggle in. Besides, the PC is use every day is upstairs and the modem & router are downstairs. There really is no practical way for me to get off the router except to use a different machine. What a PITA.
Thanks for the info, though.
