It's happening to me too, every time I try to post a message.
Sad to hear that. I took some comfort in the thought I was the only one this was continuing with. Oft times it happens to me when I click on links internal to this forum like 'Post' or 'Welcome to the Aspergers Community' to get back to the main forum index.
The forum also runs slower than I2, even though, from the test I ran, my hopping connection isn't particularly slow.
When following links in my email notifications, it happens more rarely.
I still suspect the server hosting the forum, personally. I could very well be wrong... but it is what I suspect. It seems to be very slow to respond, even though the hops are quick and relatively few.
