Okay, just to be clear, you are not expected to buy 30-50 badges!
Anyone who is selected in the badge-buying lottery is allowed to buy 3 badges. This means that people may have 'extra buying slots'. If this happens, they will buy for someone else in the group.
If someone gets to the front of the line before you do and buys you a badge, you will still stay in the sale, and then if you end up at the buying screen, you can buy for 3 more people in the group who do not yet have badges. So at most you would be buying 3 badges for others. Those people would pay you pretty quickly, usually via Paypal.
Each *group* has 30-50 people (depends on the group leader and how many they feel they can handle). That means 30-50 people trying to get buying slots. If 1/3 of those people make it into the buying room, then everyone has badges.
For sure we will wait until after pre-registration to form groups for open registration. Shortly after pre-registration, I will contact the group leaders and see if they're willing to continue their groups, or find new leaders if they have to relinquish their duties. At that point, we'll figure out if any of the groups have extra space, and if not, call for volunteers to start a new group.
However, if there is anyone here now who is eager for open registration who wants to start a new group, please let me know. We provide help behind the scenes to give you advice and assist you in setup of the group. We can open your group for new members once pre-registration is over.
