This will be CLAMP's 23rd Moodle Hack/Doc Fest. More information can be found on the Hack/Doc home page: http://www.clamp-it.org/clamp-events/moodle-hack-doc-fest-winter-2019/.
There is no registration fee for Hack/Doc Fest. That said, this is a "pay your own way" event; attendees will be responsible for their own lodging, transportation and food. The college will provide a light breakfast and lunch each day of the event. CLAMP has a limited number of travel grants available; please see the event page for more details.
