What I meant by this what a mechanism to prevent and endless series of attackers. I could see myself at S&V night with a line of hunters out the door.And to your last question I don't think anyone should be removed from the list unless they request it. Maybe you have a lot to do and don't want to be a Mark for a week. Thats perfectly fine. Adding and Subtracting all the time will be more of a big strain than anything.

I think the answer to this is found in the mechanism for establishing a bounty.
Once a bounty is posted, what happens then?
- Is the Bounty given to one Hunter upon an agreement with the Client?
- Is the Bounty posted and then "up for grabs" for all registered hunters?
Other scenario ideas:
- Hidden bounties. The exact identity of the bounty is unknown. Clues are given. This would work well in the "up for grabs" method above.
