I can imagine your shock! But qe do have an important outreach function, and most of the guys who are now registered and using the site were first lurkers (as we call them) who came in anonymously and read for awhile before deciding to take the leap.
As someone else has said, you should assume that anything on the Net that doesn't sit behind a password can be googled. Personally speaking, I'm one of the many who found the site through Google.
If you have really private or confidential things to talk about, put them on the Members' Side or just PM a few trusted friends.
