Security in Facebook
The feedback I got was extremely good, I had to answer questions for like about an hour.
My main point was to inform them about their privacy settings, how to set up an online identity and some advice on what to do if anything happens.
The audience was about 80 people, from 12-18 years old.
The presentation is in Greek, and a version 2 should be coming up later this year, covering more statistics and more advices. Click more to see it!
