It has been observed that once the user logins to the Collaborator and all the floating user licenses has been consumed he is not shown the initials (login names) of all users that are already logged...
If privacy is a concern, can you make visibility to logged in users a global setting?
I can see this scenario visible, and an admin not being around.
Having not hit our own limit, I'm not sure how SB handles floating licenses. If you are denied, do you have the option of waiting and/or being notified when a license is free, or do you just keep trying? Is there a "kick off inactive users" button for a user or an admin?
