This question, among other things, shows the limits of my big-picture grasp of Moodle setup. I have successfully installed Moodle on a remote server, and on my office server. I am interested to set up a second instance of Moodle on the remote server. Would this require a second database setup, or could it share the same database as the first installation? (I imagine that if I actually started to set this up, I might answer my own question by trial and error, but I am nervous about messing up the first instance of Moodle in the process.)
