Not always just resolved. Some people post, a Tech replies, and the poster never comes back. Someone else nerco bumping 3 months later does not help. It also makes the Blues think it already has been dealt with - because Blue post.
The never ending disconnect threads are a pet peeve of mine. Yes, the internet is a crazy mess between you and the servers and tons of things can go wrong. That does not mean the same thing that was wrong last month is wrong again this month. I realize logical people know that, but sometimes the posters seem not to. I wish they were locked after each time the issue of the day settled down. Then people who had unique issues would make new posts and get proper attention.
