Super jazzed on hitting the first stretch goal! And you bet, I am planning to hit up the first KS folks one more time at minimum, and also the mailing list one more time once we're nearing the end of the campaign.
We have the ability to do a diff and see who is new on the new campaign and who didn't come over from the old one, and how much they backed before, etc. So we can reach out specifically to the higher-dollar-amount folks from before and see if there's anything the matter. From the sound of it, a lot of them just forgot or similar.
