First of all I've been enjoying project Euler for a while now and I wanted to say thanks for a brilliant website
On a different note I recently (I know everyone else probably knew about it aeons ago) heard about Flattr a service for making micro donations to a website and projecteuler.net was the first thing I thought of. I realise there is already an option for making donations through paypal but I can't help but feel this might persuade more users to donate?
I wondered if Flattr was something worth considering? Or perhaps its already been discounted for some reason or another.
Anyway just an idea and thanks again
