I think that this needs to be defined a bit more. Since the SL forum is belly up for some reason, here is as good a place as any I suppose.
These rules do not look like what was on the forum. I am not certain about that, but those over there were not exactly perfect either so I suppose it doesn't matter.
Issue number 1.........
I feel that someone who challenges a host and loses should not get to challenge that same host again for a whole month, not just one week. Maybe even two months. He could challenge someone else instead or work on training to be better.
A host has one week between matches...of grace period....if he chooses it. And that is not listed here. I know that is different than the rules on the forum and suspect there are others.
