Can the bounty rules be changed so that users can offer bounties lower than fifty points? I think that Ask Ubuntu would benefit from allowing users to offer five-point, ten-point, and fifteen-point bounties. Some users may want to offer bounties, but they do not want to give up so many reputation points (like me for this question What are the steps to modify a filesystem (say XFS)?). If users could offer smaller amounts, perhaps more bounties will be made.
