At least twice we’ve had members join upon invitation from admins without specifying that the invite includes a group membership, only to have them gain the membership immediately upon signing up. Is there some setting I’m not aware of that could be playing into this behavior?
Are these invites are sent from /my/invited, or somewhere else? The only other “auto add to group” feature that I can think of is the email domain option within group settings:
Not sure what to say. We’ve successfully bulk invited people and added them to the necessary groups. These were just a couple of one-off invites to particular conversations we thought somebody would be interested in. Both of us who did the invites are admins but didn’t select to add the person to any groups.
FWIW, I’ve not had it happen consistently. First time I passed it off as a fluke. Second time (at least it being noticed) was another admin. I don’t believe in coincidences, ie the same fluke happening twice, so I thought I better report it.
I’ve been trying to repro this, no luck so far. Let me make sure I’m mirroring your config as closely as I can:
This category is reply/see to everyone, and create/reply/see to a single group (let’s call it foo)? Group foo is closed, you must be added by an admin or group owner? Users invited to the topic by admins are (sometimes) ending up in group foo?
