The orange trail wiki button is failing because Jim had it configured to use custom banner ad management software (ABM). Basically we had a friendly disagreement about site design, and he wanted to test to see how many people clicked the button. That's where the ABM software came in.
I imagine that after ClubTread moved to the new owners & web host, the ABM software didn't follow with it. Simple fix, just remove the button or modify it to link directly to the trail wiki.
I told Jim a long time ago that all web forums hit critical mass at a certain point, where the more... vocal users start to weigh down the site and push away the good content. In my opinion the site crossed that mark about three years ago. It would take modifications to solve that problem, likely bubbling the good content, TRs, and trail discussions up to the forefront.
