SMART on FHIR Profiles

Could someone direct me to where the conversation about SMART on FHIR Profiles is taking place?

For the common clinical data set, rather than creating/maintaining new profiles we’ve aligned with the Argonaut and US Core. Please see http://argonautwiki.hl7.org/index.php?title=Main_Page for details, and the #argonaut stream of https://chat.fhir.org for discussion.
