If you click on the username to the left, in this case "VKB", a profile page comes up and you can see when the person last posted. VKB hasn't been here since the day they posted.
We've only had a couple of people with Scleroderma that I can remember, and they seemed to post mostly in Lupus. A search shows they are few and far between.
You might try the Scleroderma Foundation at https://www.inspire.com/groups/scleroderma-foundation/
- they seem to have a discussion group there.
Hope you have a great day!
