Very nice to see the site still running, it is a great piece of work. I think one of your main problems with donations is that people think the site is a official Cinni dev site and also the fact that the text for the donation address is to hidden at the bottom of the page and the color against the background makes it almost impossible to see unless you are looking for it. I would put a small article on the site that is kept permantly on top above any new updates, that explains the site is a free community project for Cinni and is not supplied by the devs and that donations would be appreciated to pay hosting costs and for your time.
