This is not a venue where you can advertise your product or services, and definitely not a place where you can promote affilliate programs or MLM scams. Avoid personal discussions. When a thread becomes more of a personal discussion between individuals, it's time to take it to private email. While we may have differing opinions let's keep this a friendly discussion group. Your name adds credibility to your words.
Long signatures can clutter up the digest and make it hard to read.
If you are replying to someone else's post, include only as much of that post as necessary to make yours understood. Avoid sending incredibly large messages - they will be blocked by the server. If you need to send someone the works of William Shakespeare, or a .jpeg of your latest project, please do so privately. Please do not post pictures to the list. Finally, be civil to each other.
