Since we do have such a broad span of conditions and topics, what about something that tries to capture the essence of what we are all dealing with:

ChronicLife

ChronicTalk

ChronicIssues

or something with Chronic in the name, that wd identify us to people searching for such a support group?

Or something even simpler:

IllnessTalk

Disorder(ly) Talk, or Disorder Central?

Just trying to think along the lines of KISS (Keep It Simple, Stupid)
