I have a hard time understanding what Confluence guest groups are for. I understand normal Confluence groups, but am I right to think that Confluence guest groups are only a different (and not shorter) way of adding multiple guest users to a space?
I really mean add, not give access to: instead of adding guests to a space one by one, you can add them to a guest group, and then under the space's settings, you can add all users from that group to the space at once. However, adding new users to that guest group won't give them access to the same space; you'll need to add them one by one.
Is this really how it works? If yes, why would I use a guest group instead of adding those guests to a space directly?
