Beyond being family friendly and avoiding spam, there is really only one rule: THREAD AUTHORS SET THE RULES FOR THEIR THREADS. A thread author is defined as the individual who starts a topic by pressing "New Topic". Details are provided in this forum, but that's about the simplest most effective rule there is.

A mission statement is also provided. Also there is admin stuff like telling you to clear your cache so that ongoing software improvements don't ruin your viewing experience and maybe some helpful tips like how to show equations and youtube.

Users are invited to post feedback threads in this forum.
