As Zeos said, at the moment you can support us by buying the alpha. We are a regular company (based in Slovakia/EU) and there would be some issues with donations vs. accounting, for one thing.
For other types of support, like funding a specific project to be developed using the Outerra engine please contact us directly via email (contact at outerra.com) with description of your idea(s) and goals; things like these aren't usually discussed on the forums unless you want to launch something that is supposed to gain a wide public support and funding (like a Kickstarter campaign).
