@Be..anyone, what is the idea behind the FIXME that you have added to the documentation?
Help talk:Structured Discussions/Administration
NUMINGROUP is a magic word, it is the number of users in a given group wrt Special:ListGroupRights. In some cases the name is obvious, e.g., there are {{NUMINGROUP:bureaucrat}}
= 33 bureaucrats on this wiki. But often all my attempts to find the name for this magic word fail, i haven't tried it for suppress or flow-bot. Tests:
{{NUMINGROUP:suppress}}
= 0{{NUMINGROUP:flow_bot}}
= 0
That's probably a bug. I'll ask for an investigation.
Thanks for pointing it out!
{{NUMINGROUP:flow-bot}}
=1
All registered users have the "Create Flow boards in any location" right.
Maybe User:Flow talk page manager is a proxy for this purpose (the 1).
Both suppressors and oversights groups have the suppress right.
This documentation is for all users and administrators of Flow, not just MediaWiki.org. In my opinion, we shouldn't put too much emphasis on MediaWiki.org's configuration (e.g. which groups have which rights, how many users are in the group).
I've also fixed some other issues. E.g. I documented flow-lock, and clarified rights vs. groups.
I also removed "The action link" part. It seems redundant; in all cases, users that can do the action see the link (if not, that's a bug).
Trying to decode that message, the suppress = 0 is actually correct here at the moment, and not another case of nobody knows what NUMINGROUP image reviewer is, because it exists only on commons.
#suppress has an incoming link from commons as of now, ditto #rename_2, cf. c:Commons:Flow bots + c:Commons:Suppress. There are two corresponding incoming links from Meta (not using the subsection fragments, oddity in {{softredirect}}).
Good to know, thanks!
