I have a Group (Group A) with about 100+participants. I also created a workspace when I created the group.
Later,one of the participants created a workspace under this group. So, I now have 2 workspaces under this group.
I want to give access to some participants only to Workspace 2 without giving them access to Workspace 1. How will I be able to do that?
Go to the second Workspace and if you are a coordinator you can add participants - the available participants will be the group you have created - add the users as normal to the Workspace and you will be all set.
What you are trying to do is have 2 Workspaces drawing members from one group and that is OK if and only if the master workspace - matching the group name is going to hold all the users and only a subset of them will be in Workspace 2. If you wnat workspace 2 to have users that are not in workspace 1 then you will have to create another group and use that to populate the Workspace 2.
