I ran an IndieGoGo, which is long since over. Other than the IndieGoGo I haven't given much thought to setting things up so people can contribute, that's very kind of you to offer. I'll investigate adding PayPal or some alternative when I have a little time. In the meantime, you could send me Bitcoin at: 17ukkKt1bNLAqdJ1QQv8v9Askr6vy3MzTZ It'd be much appreciated!
