He has a donate button on his homepage. I wonder if that brings in something? Anybody here who ever used a donate button on their website and can tell something about it?

How does one even receive 'donations'? Is that like getting paid? Do they have to create an invoice for tax reasons? How is it taxed?

It would be nice if there was a number, how much is donated per month. I can imagine donating something. Depending on how much cash flow there already is.
