Arisia'15 is over. Please visit the new convention site: www.arisia.org.
Pre-Register for Arisia LARPs
If you're interested in playing in one of the many live-action roleplaying games, you can sign up using the ARISA LARP Player Signup Form at http://www.arisia.org/LARPPlayerSignup.
Doing so will give the GMs a better idea of how many players they've got coming, and a chance to answer questions you might have.
This form will be open until Thursday, January 15th.
