I've asked MN Admin & they've asked that a post a thread on Site Stuff to guage interest.
On a recent thread it appears that they were quite a few of us who have IBD, (Crohn's disease or Ulceritive Colitis) and other conditions either associated with this disease or other AI disorders.
If you'd be interested in this as a new topic under Health please post on here. The more responses this thread gets the more chance of it happening.
Would be good to have a suppprt thread out there.
