I'd like to donate but...

How long will contributions via planetaryannihilation.com (PayPal) be accepted? I just got a new job and expect my first paycheck in about four weeks or so. I'd love to contribute and get alpha access ($100) but I'm worried the donations and rewards system currently in place will stop before I get paid. I'd have donated to the kickstarter page directly, but I have been unemployed for the past couple months and kickstarter donations are now closed.

Thank you for your time.
