Creation of group leaks name and included numbers to participants before any message is sent

[kannes]

I created a group just to test how creating a group works. I added some random contacts that showed as TextSecure users. Then I decided, ok, creating groups works and went on with my day.

Later I received a message from one of the users, inside the group, asking about the purpose of this group.

At no point did TextSecure indicate or warn that the mere creation of a group was a "transferred" action. This lead me to leak the numbers of completely unrelated strangers to each others.

Please add a warning or dialog that a group is immediately communicated to all participants, even with no message(s) sent.

I see, do you have an example of other messenger apps that work the way you're requesting?

WhatsApp acts like TextSecure in that case.

Thanks for taking a look at this. I have not used any other messenger app, so I don't know how others do it.

I would suggest adding text on the screen right after touching "New Group" (translation might be different) where you can set the name of the group and its participants. In its initial state there is a lot of space (at least on my tiny phone).

Maybe we could add an anonymous group/BCC-option where I could write to all chosen peers at once but they could only see/answer me. That would introduce a clear distincion, prevent misjudgement and on it's own a useful feature.

@riyapenn Could you add a few words what close means here?

After creating group, a conversation is created and it states that you 'Updated the group.' (iOS users see 'Group updated.') All users see this new group.

So this feature now exists.

I don't understand how that answers the issue. If all users see the group, surely they see each other?
