As the group manager you have a very wide range of options. You can
ban people, remove posts, etc etc, as with much other "standard" forum/
group software, but it is a great deal easier to use, and you don't
need to worry about servers, backups, domains, etc etc etc. Lots of
options and possibilities, and private ( restricted access) groups are
completely closed to anybody except members.

Very convenient and useful.
