There's 106 sitting out there waiting for approval. Many of those are from China, Russia, and other countries. Many of them are from the same group, using various usernames but ending in the same last few letters like kew or dem, or they're from the same African nation. I'm sure they can look at the forum, but without registering, they can't get much personal information unless someone posts their email address, home address, or phone number in a thread.
There are lots of people aware of us and read us without registering. I've been talking to someone who's doing a 7730 upgrade. He's been reading our threads, especially f85gtron's, and learning from our members.
