Some groups you can read w/o being a member, others are closed to non-members. I belong to Simply, Jeff Berger's site, Orient Village Life, SXM Naturism and probably 1 or 2 others. Some I applied for, others asked me if I wanted to join (and I thought about what Groucho Marx said). I also belong to several political groups and motorcycle groups. But, I still check in here daily & enjoy learning new info.
