hello everyone

im a new hnso for my league, and in order to help a fellow skater to buy new skates, we decided to organize a fundraising ref/nso clinic.
i have to give a 1h lecture about the nso positions. As nsos yourself, can you tell me what is the main aspects that you would like to see in a class like this?
my main problem is that, if i talk about all the paperwork would be really boring, and i only have 1 hour to speak.
we have schedule practical exercises later with the refs and doing a mini scrimmage also.
thanks everyone
