I want to place a bounty of 200 on an existing answer to thank someone for helping answer my question, but when I click "Add bounty", my only option is "500". That is too much. A previous bounty went to another user. How can I award a smaller bounty?
We now double the minimum "spend" for successive bounties on the same question by the same user. So if you started at 50: your next bounty on that question has a minimum of 100, the next 200, the next 400, the next (max).
