I've joined in this coffee-maker thingy, and I set up my paypal account too, so...
ko-fi is a page where you can create buttons for donations, "buying a coffee for someone".
If you want to support me contributing and helping with some money you can make both of us happy, and I'll to appreciate dearly the detail.
If the button doesn't work, tell me about.
I leave the button in my page profile. Thanks for reading!
