I'll assume that you mean this year's burn.
Fill out the questionaire on the main site. Be sure that check off those departments that interest you. Get on the mailing lists.
Join a large theme camp and be their total dog, so you can get in early and set up camp.
Find an artist who needs help setting up a placed art piece, so you can get in early and set it up.
And please, don't get the early entry and use it to party. That's just so sad.
And expect that volenteer departments, theme camps and artists will have a process by which they decide you are serious about helping.
