I am organizing an editathon at a conference at the University of Canterbury and would like to be able to have attendees register as new users on Wikipedia during the session. There is currently a block on the whole IP due to vandalism I believe or because it's a school.
Event Time Frame: Saturday, September 17 - Sunday, September 18 from 9:00am-4:00pm New Zealand Standard Time
Expected number: 50
List of Wikis: Wikipedia
Can get the IPs when I'm on campus.
