This site has been around for a long time. Offers DVD's etc of past circles. Requires membership for parts of it. Today, as I am posting this, great new circle, celtic cross. Site is constantly updated. I learned of this from email, but I don't remember signing up for email notification from the site. Link below is to new circle, made today, and my email states it took under 10 minutes to appear.-Candace
PS: here's the link to a circle made on 8-8-8 on the same site.
