This policy is starting to confuse me quite a lot. We are instructed to add to existing threads when possible.

Yesterday, a thread that was started in order to have a little fun was consolidated with some other threads in a way that made it not fun any more. So I looked up an old thread that was fun, thinking I'd put something I thought was funny on it in order to have some fun. This was a thread that had no acrimony on it and it was (is) a good natured, funny thread.

The thread in question was started in October of 2002. The last post that was made to it was made in October of 2002. Two weeks ago, when I looked in on the thread in question, it was still open for posting. Today, when I looked in on it, it was closed.

What's really going on here? Are we supposed to add to existing threads or not? Are there specific rules about what types of humor are permitted here (other than the rules about personal attacks, etc.)? If so, would someone please point to them in the FAQ?
