First of all, this isn't vB. And while this software does have a "Watch Topic" option, I don't know if there are any theoretical limits on how many topics can or can't be watched. Second, this wasn't a "clean" installation of the software, but a conversion. Not all conversions go as planned, and while this conversion did go fairly smoothly, there were a few minor hiccups that needed working. Third, as part of the troubleshooting steps, it's not an unreasonable request to ask to clear all watch options, and start from scratch to see if the behavior persists or clears up. As I stated earlier, there really isn't a reason to watch every single topic you post in as the search engine that's installed is light years ahead of anything we've used in the past. And you did state that all topics were listed in your UserCP, but not listed in the recent topics block in the sidebar. Since this is working fine on my end with the test account, I have to suspect that there is a limit to the number of posts that can be tracked and simultaneously displayed in the sidebar, which would not surprise me in the least. Especially with the trend by the developers of the software to keep queries at a minimum for optimum forum performance.
