Oh, I think there are fans of Christie's around here. I'm certainly here. Or I think I'm here. <_< And I don't know a better forum.
I think what happens for some of the "classic" models is they aren't as popular, so fewer people post less often, and also visit in general less often. I don't visit the forum everyday, for example, and if the Niki Taylor (Karen Mulder, Stephanie Seymour, Valeria Mazza, Ashley Richardson, ...) thread slips past Page 2 or 3, I won't catch it. And the forum moves fast. And I don't always have time to make a post. Even a quick reply.
Don't sweat it. The lurkers love Christie, I'm sure.
