Since it sounds like you're not organizing a Burning Man regional group event, your event would not be listed at all without approval. If it were to be approved, it would appear just as any other thread in that group (same way the whole board works). Posting on ePlaya is just that, it's posting on a message board. It does not guarantee that certain individuals (or anyone) receive an invite. If you want to invite a specific individual, you need to contact that person directly. Unleash your inner radically self reliant rockstar and read the post I'd linked, and check out the regional network linked in my signature (as well as previous posts). There you'll find information, instructions, and contact info. Good luck!
