Thought it was my imagination. Glad someone mentioned it. Access via the "Hop To" pulldown menus is very long, compared to other forums.
I'm using IE5 on both my office computer (near T-1 speed) and at home (28.8Kb), both connections result in delayed access to the United Forum. This evening at home the Forum opened up and there were no active threads at all (I use the "Last 2 days" setting). When I manually refreshed the browser, everything appeared normally.
