I have entered a room, but it is completely empty. What happened?
If you encounter a room with no entries and no members, it is possible that you have accidentally opened a new project room instead of entering an existing one.
In this case, delete the unintentional room again. Only active rooms should remain in the system. See also: “How do I delete a project room?”
Now, look for the room you wanted to join and enter it. You can use the room search on the CommSy homepage.
