I think the figure of 100 includes members who have left us; one 'real' member (milleplod) and various sys admin accounts that were set up during the creation of the site.
We still have one sys admin account to allow The Creator to get into the site if they need to.
We also have two 'dummy' members, accounts created to allow the admins and mods to see what the site looks like to you mere mortals out there; we have a different page view from up here in the gods, even when we are not in admin mode, so it is important that we can see the world the way you do from time to time.
