I agree about the challenger list, Ranketsu was running that scam before where she told me she had so many challengers in front of me we would not get to fight for months and then when Rakudo asked she told him she totally had fought and beat me every time I asked to fight. After actually fighting Rank I think she was just a serial liar but it could happen again, and the victim might not be someone everyone hates that time.
Inheriting the list is good too, I don't think it would be fair if you had been waiting 6 months to challenge for a bijuu and then the person before you on the list beats the host, and you don't here about it because you are away for the weekend and when you get back you're back on the bottom of the list again.
I don't know if you should HAVE to set a date for the fight, sometimes when I had challengers I would just tell them "Well I should be able to do it sometime this weekend let's plan for then." Though then you could just list "weekend of whenever" I suppose.
We should just have 9 topics, one for each bijuu, that the current host makes (maybe wait for Zen to give them all out first) that way they could edit it freely. Then if you lose it you would delete the topic and the new host would make a topic they could edit. I think that would be fine.
