The hubzilla users forum has description text of its purpose:
Hubzilla Users Support
hubzillauserssp@zotum.net
This is a channel/forum for users support - not admins questions
Please could similar descriptions be added for this channel (
https://zotlabs.org/channel/hubzilla-development) and the other (
https://zotlabs.org/channel/hubzilla)
A bug (
https://framagit.org/hubzilla/core/-/issues/1475) was recently posted, but unsure if either channels should be used instead.
