Feel free to post your questions here. We're all glad to help. On the questions you posted so far - The people who buy tickets will be able to participate in the RSP. You will get a link to a form to complete where you can specify the pins you want in the order of priority, up to 3 of each pin (likely more for the mysteries). They will then run the RSP and assign out the pins based on a combination of priority specified and how many other people want them. You'll then get a communication back with the pins you were alotted and will be charged based on that. (But you can cancel/return pins if needed.) The pre-registration day is simply an opportunity to register for the event and pick up your pins the day prior to the event so that you don't have to spend time doing it at the event and don't have to carry your pins all day. There is also pin trading opportunity (not the boards, just with other attendees) that day for those that have checked in. Hope that helps.
