As you know, Casos-Aislados.com it's an initiative completely personal, that doesn't want to depend of any organisation, no matter which. Sadly, after many times having the website down due to attacks to our server, the promise to keep this website online will cost more money than thought at the start.
If you want to donate a different amount of the one indicated in the form, you can send a message from the Contact page. . All the donations will be reflected in the website for better transparency.
And remember: the contributions will only cover the server's expenses, the workforce on the web is free. Casos-Aislados.com does not save ANY Banking data of yours on your server, the whole transaction is done externally and safely on the Paypal website.
