A common complaint/issue with the ZUG site so far was the refresh issue with the "who's online" block, and the fact that on each refresh would cause trouble when trying to post to the forums via the Zaurus.
I have figured out a quick and easy solution to that... I realized that when in the ZUG forums, all of the blocks on the right (Calendar, ZSI Updated, Linux news, etc.) don't appear. This allows for more viewable room when in the forums. So I simply moved the who's online block to the top right, and viola, problem solved!
