Thanks Nick, but I'm not quite sure I understand your advice. Let me clarify.
"...it is advisable to remove the information..." - the "BBB Admin Panel" plugin only stores the BBB url and secret key to connect to the BBB server and perform operations like meeting create, join, start, stop, delete, show recordings. It doesn't store any additional info except the meeting creation properties AFAIK.
"To raise a database on the server with Bigbluebutton..." - I think additional DB or records wouldn't be necessary. The info needed is presented in the bbb-web.log files and could be parsed with the bbbattendance.py script.
"And the entrance - the exit of the client..." - I can imagine that after the meeting ended, nothing triggers automatically.
Let's say the wp administrator (or another role with proper permissions) clicks a button in the wp frontend or backend page and triggers the
bbbattendance.py execution on the BBB server and the download of the csv file created.
Is that possible?
