The idea is a good one BBW. Who ever creates a tournament, could send out seperate invites, if they decline then fair anough, im sure there would still be enough to take part.

There is still the problem of rated tournaments though as mentioned earlier.

Also that people in fellowship tournaments who leave a fellowship, can still carry on there game and win, surely that is not right for the members of the fellowship.
Like BBW says, tounament creators should be able to make sure there tournaments are run fair for all in them.
