This message is offtopic, but I don't know where I should ask about. In the page of ISC, in section "Tutorials" I can see some interesting topics: http://www.isc-events.com/isc12/tutorials-100.html
But the ISC web does not contains more information nor documentation (if exists). Attended some user of the forum the ISC tutorials? Exist any type of presentation, examples, etc? Where is it?
