Question about "Live" (????)

Hopefully this isn't a dumb question.

Do all ATS forums show up in the "Live" feature, or are only selected forums picked up by "Live"?

Sometimes when perusing other ATS forums I could swear I see topics which never crossed the Live listings (one of the places I usually hit first here on ATS).

Tis a good question and one I never thought of before.
Looking forward to the answer.

Hmm, what does that tankard looking icon actually do? I have never used it before.
