www.justgiving.com this is how people sponsor me this way I know all their cash donation go straight to my charity and my sponsors give gear directly to me, it works for me. It's not that hard to do speak to your charity they'll help you with what they want and expect, 99.9% of people are honest, it's the small minority that screw it up for the many. If you want to know anything about how I fund raise or how my sponsors will get coverage just drop me a e-mail or pm and I'm more than happy to give you a hand, all it takes is a bit of effort, but you can make major changes for other people less fortunate than yourself.
