Here are how bounties work:

Any member can request a bounty on another member. Once requested, the requester must state the reward and the objective of the bounty, and if they want, a reason behind it. They would post it at the Bounty Request Thread and wait for a response. If they respond to it, respond saying it is ok for them to take it. They will then carry out the request and notify you when the deed is done. From that point your will complete the transaction in the Profile Modification Thread in the Profile Modification Forum.
