EDIT: Also, these changes will take effect for everyone who has already pledged at these levels. Though if you could, please switch - if the old ones have 0 pledges I can delete them.
Unfortunately I can't change the pricing structure in place, but based on the feedback we've gotten so far I've added a set of new rewards - all of which are better than their previous ones. :)
$15 - A license and acknowledgement on the contributor list
$50 - A license and early beta access
$100 - A license, early beta access, and participation in feedback rounds
$200 - Two licenses, pre-beta access, and participation in feedback rounds
All the higher rewards will also of course include participation in the feedback rounds. Ultimately, this should address people's concerns of buying something before it exists, but providing the opportunity to be a part of it at a lower price point.
