As far as we can tell, there's no unusual computer behavior coming from the server end of things here in Colorado. The more people that are using the board at once, the slower it is, and the monthly Google crawl takes up some bandwidth too. "Systems are working within normal operating parameters," as the computer on the Enterprise would say.
We always wonder when things get slow, too, and most of the time it ends up being an internet problem....a slowdown at a local (or distant) hub on the internet backbone, a router gone down in Denver, etc.
Keep letting us know when things look screwy, though -- sometimes it is on our end.
