We setup a system to find discussions that are popular and include those in the newsletter. Out thinking was these are probably discussions that members who are not here on a daily basis haven't seen and might find interesting.
If you are here everyday reading many of the threads then the newsletter won't be of much value and opting out will save you some emails in your inbox.
If you don't like the newsletter, please unsubscribe (see my previous post) and don't mark our emails as SPAM. It's hard enough being a small fish in a giant ocean, your help is greatly appreciated.
