I am a newcomer in the field. Due to covid-19, as a teacher I had to follow a fast path course into the mutitude of toolls available for assembling people together online with the idea of teaching them something worth it. I chose Jitsi because it is approved by the French Education Ministry, its ease of use. Last but not least, my sister uses it on regumar basis back in Montreal, Quebec. I am located in the parsian suburbia, 40 km north of Paris.
Since then I have used jitsi meet 4 times and most of the time I as able to do what I expected to do.
However I had the the rather inconvenient experience of a participant bullying my class, which at first I did not really know how to handle, and then when I decided upon kicking him out, that person was able to kick me out in response.
Thus this participant had the last word as I could never get back into the class I had planned and organized.
In order to avoid this to occur again, I would like to know what have I done wrong as the administrator of my class which led to a person being able to hack my class?
