I think there should be a rating system, just like the system used for players left after games, for you to rate the host of a tourney you just played in. You can use such features as:
organization- poor/fair
attendance- poor/fair
execution- poor/fair
some for starters.
I came up with this idea because many times I get a PM 1 to 2 months later for the next round to begin and every time the excuse is " sorry for the tardiness, I been busy". I really hate reading PM's and joining games 2 months later. This way, when you sign up for a tourney, you know from the rating what kind of host you are dealing with.
