Hi Shamim

Yes the user shows in every groups (I created 10 groups for my tests).

What I did in order is the following:

In my dashboard, Recipient tab, I allowed users to add themselves to groups.
Then on the front-end I logged in as a test user, and I could see all groups in the Parameters tab that I had created in the back-end. Fine.
I sent a message to a group. Successfully sent. Back to his Parameter tab, all groups were checked. Meaning the user has joined all groups. So I went to the back-end and could see its username in every group…

I deleted the user in every group from the Dashboard, recipient tab. Then I unchecked ‘Can users add themselves to group’.
Second message sent from the front-end to a group. This time the user is not part of any group (in the dashboard).
So it has something to do with that option allowing users to add themselves to groups.

I will keep this option unchecked and try to assign the user to a group in a different way.
