Hi Ben,
This has been asked a few times in the forum. Camelot itself has no user management.
However Camelot can be installed on 1 computer and as it's a Web Application, it can then be accessed through the URL by other computers assuming that the other machines are all on the same network and the firewalls on the computers, and firewalls between the computers is setup to permit TCP traffic on the port 5341.
There are no controls around who can do what in Camelot.
So, yes you can have two people on different computers accessing Camelot, but it does need to be configured correctly for that access.
Regards
Heidi
