Registration is simple and easy, and not that personal. Guest who have a problem giving an E-mail address and their real name, most like won't be a productive member of the forum. The guests should be able to read and search the forum freely, it's intend to inform and help. Those who like what they see, won't have a problem registering, since we keep it clean of all illegal activities, no reason to expect bad things.
Maybe some of the Fake-Users are people who don't have their own internet access at home, perhaps its from school or the public library. Would still think there is some way to get an E-mail account, without paying for it, or already having one, but never needed to find out.
Anyway, this site is great, and should continue as it has. It will sell itself to new users, as it has in the past. The people who try to hide, and sneak past the registration should be kept out, as the bulk of them likely have bad things on their minds. These are the ones who don't seem to have much knowledge of model rockets or radio remote control, electronics, or much of anything, but need to know how to do it in a hurry... Keeping the site clean and spam free will attract more quality members, than just letting pretty much anyone through, and trying to clean up the mess later. I'm sure the moderators have other projects to work on.
