Allow extending bounties by topping them up (within limits)
So I asked this question and it looks like no one has an answer for it. I put a bounty on it, and still no takers.
I know that I can't get that rep back, but if there's no answer by the time a bounty is over, I think the OP should have a mechanism to extend the bounty... even increase it. Having give up X amount of reputation points to find an answer and get none (not even bad answers!) may be fair/reasonable, but it also kind of sucks :P
