Also known as: checkgroups message
A control message carrying the authoritative list of groups in a hierarchy, each with a one-line description and a moderation flag. Administrators compare it against the server's active file and add or drop groups to match, which is how a hierarchy distributes its canonical group list. The Big 8 board issues one periodically. Most sites process it semi-automatically and review the deletions before applying them.
