I knew what you meant about the "community." Kind of like the site that Callaway linked to to bring me up to speed on the McCarthy thing - to me all those kind of sites are hype, either promotional or political hype. Those things are the scourge of the internet, in my opinion, like commercial television.
When I saw her at an MDA charity function (I was still doing volunteer work for them, then), it was sometime in 2000 and she was probably a size eight, but like you said not "celebrity model material" anymore. Still very attractive, though. She was not there because of her modeling career, either. She was doing a stand-up comedy routine. Her best material was making the audience think that she was about to get into trouble over telling a really dirty joke and the punchline turns out to be totally "G-rated." I think she had just finished a movie, maybe the one you were talking about.
When I researched the vaccine thing, there was no evidence that it could cause symptoms of autism. I did not know that she had started it and appeared on Oprah, etc. Shows you how much television I watch, eh?
