I was unaware of any VATSIM rules prohibiting the closure of airspace during my prior posts, and I am sorry for adding to the confusion of this thread.
Ryan said it the best: "Out of respect (CoC A.1) for their group, we ask that you park up on the grass and enjoy the show, just as pilots in the real world would do."
For those who are wondering why I am so involved in this post, let me explain:
On July 2nd, in the event forum, Nick Warren asked if there would be an Oshkosh 2018 event. After a few days with no response, I asked Jamar Finch, the EC of ZAU (And a good friend), if OSH 18' was planned. He said that it was not on his radar, but he would love to hold the event again. Since Jamar was not there for last year's event, and I was, he asked if I would help him out in making VatVenture 2018. I helped explain how Oshkosh works in the real world, and how he could improve the realism for VatVenture from last year. He was grateful for my help and put up an amazing event and NOTAM packet in the forums on the SAME DAY we talked. Later on, I contacted Jamar about a unique way to spice up the event from last year by having the FSX Blue Angels perform at Oshkosh during the event on the network. He was really supportive of my idea, so I went to an old friend from the FSX Blue Angels, named Ben, and asked if he and his team would like to participate in VatVenture 2018. He was also very fond of this unique opportunity, so I set up a meeting time with Jamar, Ben, and myself to hash out the details of how the demonstration would be integrated into VatVenture 2018. At the end of this meeting, it was my understanding that OSH would close to traffic at the end of the event (2100z), so that the FSX Blue Angels could perform while connected to the live network. (At the time we didn't know that closing OSH would be against VATSIM regulations). Pilots could view the demo by being connected to VATSIM, and parked on the grass or ramp at OSH.
Since I was one of the few people with this knowledge, I felt that I could help by answering some of the questions posed by members in this forum. Evidently, I should not have provided answers to these questions, as I am just "some visiting controller" who doesn't know anything about this event.
I will concede that this issue could've been handled better by having Jamar answer questions based on information discussed in the meeting, rather than myself. In the future I will make sure to let the ARTCC field questions regarding their event, no matter how much affiliation I have.
