I was meaning "discussions about quality team: members, procedures etc."...
More in detail:
Can't find "About development" pinned topic
Discussion about this community, its organization, how it works, and how we can improve it.
..."discussions about QA on dev.nethserver.org"
People involved in an issue tracked by GitHub/Dev post messages in the issue tracker. If the issue is related to a discussion here it already has a category assigned: usually #bug, #feature or #support request.
If the QA discussion is not related to an issue tracked by GitHub/Dev and does not fall in the categories above it's probably about the QA team, thus #community.
