It's *working* for me, but it's gawdaweful slow. So is pulling e-mail (I timed out repeatedly pulling a 1 meg e-mail down).
I'm switching to Pair.com - I'm fed up with CIHost. Too much downtime, too many problems, and primarily: not enough communication. They've moved my server several times now without telling me (and changed my IP address), and they just don't ever tell their users that they're doing something that may disrupt their business.
Just my take on the deal. On the other hand, it's really easy to get WWWThreads working on CIHost (a bit easier than Pair). Pair's performance is noticably better, though.
