It works, thanks.
We are evaluating your chat sw. We had a meeting chat last week with 30 users and worked ok. We have different subportals for different class ranges. In every portal I created a chat room but when we "select room" the list shows all room created in all portals. If a student is registered for a subportal but is not registered in other subportal he can enter any room.
I think the room list must show only the rooms created in that portal so the users in that portal could enter those rooms only.
Thanks.
