[Utah-astronomy] How to volunteer for Bryce + camping

Can someone remind me how to volunteer for the Astronomy Festival at Bryce this year? I love to take my scope down (10" SCT) as I have done in years past. I would also like to get in on the free camping at the group campsite, if that is offered again this year. Any help? I did see a spot to "Add me to the list" on the SLAS website for the "special star party" on the calendar. Is that the way? Thanks, Dion
