hi we now use bigbluebutton hosted on our server and everything is very good
but i have many teacher , students group and subjects so we use many files.
there are only one preload file i can put it in the class and also when teacher finish session he can't back to the same session again so can't find the uploaded files in the last session.
my question is how to make bigbluebutton session open the same session every time so teacher can find the files uploaded before or how can i pre upload many files so teacher can find all files without wasting time in uploading files?
