If you remove the smilies, and it is hard to tell what is fact and what is fiction, don't post it. Humor works best when it is pointed at oneself. Keep commercials to a minimum. An occasional post indicating an item you wish to sell, buy or trade, a new product, or a service is welcome. Weekly or more frequent posts of a commercial nature are not tolerated.
Large posts are to be avoided.
If you have an information source that you feel would be useful to the list members, send the web page URL not the entire source. If the information is not available on a web page, ask on the list if someone would be willing to host it for you. This is in consideration of list members who pay per byte for downloads and the time of people who are on slow links. It also saves storage space for email and allows updating the source without updating all the list members' email stores. More rules may be added at any time.
