Awesome site. My wife has Crohn's and I've been thinking how nice it would be to have a site like this. We'll try it out. Also the link in the title is busted, but just going to the domain works.
not working for me either (Also SF). From here,
blog.crohnology.com CNAMEs to sfibd.posterous.com, but that doesn't work for reason's unknown to me (IP returned is 184.106.20.99)
