I'm trying to raise money for cancer research - anyone who donates will get the secret link to my embarrassing video. And if the total gets to £1200 (from its starting point of £944) I'll just put the link on the fundraising page so everyone can see it. Money goes to cancer research via the Just Giving Page so even if the link has become "public", please still consider a donation if you can afford it --- cancer is bad news and we should be fighting it...
