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 ($100+) 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.
