Say I have 10 people in my Group. They are assigned the role of "everyone." That role has the ability to chat. All 10 members log into SL and open the group and start chatting. The owner now wants to change the "ability" of the "everyone" role so that they can't chat. She goes into the group profile, selects the "everyone" role, unchecks the chat ability and clicks "save." Will all members with the everyone role instantly NOT be able to chat? Or, does the change only take effect when the members log out of SL and back in? Thanks!
