FYI I stopped using the ST forums because it used to EAT my responses too often. Click submit and get an "unknown error, try again, or click here for help" and then some help about setting up my windows server. I don't have any windows servers.
I decided to give the new forum a new chance.
The reliability I cannot estimate yet, but the usability has dropped even further. Clicking on the "forum" list gives a view where I can see three posts with their first few paragraphs. That might be useful for a forum-manager who is expected to monitor most of the posts, but for me as a casual contributor I would like to decide to read or not read the topic based on the title. And then have a list of say 20-30 titles that I can scan to see if something is interesting for me.
