Hi, this is a friend of Farsthary,
Due to troubles, you can not donate through paypal anymore. In the meantime, if you want to show gratitude, please support the blender foundation and improve your knowledge by buying quality learning material in the blender shop.
Moreover, the foundation may support Farsthary in the future, so please send an additional email to the eshop so that they know you support them thank to Farsthary. For people interested by animation, I also advise this really helpful book.
