Hey, thanks for interest in donating to the project.

I'm Povilas, the developer from the linked blog post.

If the donation is less than $100 you could setup a monthly donation on GitHub and then cancel it after the first payment.

Otherwise, you can contact me at "povilas@radix.lt". To verify the authenticity of this email address you can view my GitHub profile at https://github.com/p12tic, or check out https://github.com/p12tic/xorg-xorgproto/tree/p12-gestures branch and verify the author email of the last commit in the branch.
