The idea I'll throw out there, since I was redirected to this forum via PM, is that rather than a Jounin tourney, wouldn't it make sense for more of an arena sort of thing? A place for jounins online to gather and just duke it out.
I know, the Main Zone is a decent place for that sort of thing, and the perfect location to host this sort of thing, but to make it more interesting winners of fair matchups by appointed referee(s) could be awareded DP or a "point". With DP, simple enough, you get DP.
With points, if you get enough points, you get to be "invited" to higher levelled fights where others with similar point values are matched up against you.
Yeah, complicated I know, but this is all brainstorming no?
