Bull caca. From a technical standpoint, it's easier to find out how many people signed up than it is to determine the number of unique visitors. Some pointy headed nerd (such as myself
) knows exactly how many people have signed up. The software developers who built the site(s) are working 24/7 right now and they know certain things for sure, even if they can't make the site run well. One of the things they know is the number of people who have signed up.
