Thank you both. It's not the subject matter that is the problem, I could teach someone GIS easily if they were sitting next to me. Its my anxiety. Public speaking as never been my thing (despite my love for talking lol). I am just a completely different person when talking to large groups of people, and even though the training will be virtual, I am still mentally freaking out already.
Not to mention, I have to give another presentation next month at another GIS conference... so its just a lot for me to mentally prepare myself for.
