Sites that require you to sign up and become a member before you get to see any of the topics/forums. I can understand why you have to sign up and become a member if you want to take part of posting but why hide everything so a person can't check it out before they decide to become a member.
Another annoying thing, signing up to become a member and then not be able to do anything until you get an 'OK' to be part of the group and then having to wait until the next day before you finally hear back. By that time I'm off surfing somewhere else. Make it fast and quick or don't require it.
