We allow visitors to come into our lans for free. However, once a visitor does go on a computer for more than two hours in total, we have to charge the visitor the entrance fee. Visitors also have to follow all the rules above, and they have to make sure they do not disturb any of the L3 attendees as well. That also includes badgering lanners with questions!
If you do have questions, please ask the admins as we will be able to answer them.
