Gutting, though if I had a KS that was £15 short, I'd be on the phone to a family member or a friend offering them the £15 to finish it. That was a bit silly....
If it really was that much short, I'd pledge more immediately and thus be one of The Ones who pushed it over the line; to be fair The Ones would probably include the majority of this forum. We are after all, The Elite.
