[Kevin]

Just want to share a cool site
challonge.com

It allows us to easily run tournaments with professional systems, like system Swiss. It also provide the buchnolz or what it is called, the tie breaker system. It also provide single elimination and double elimination tournaments.

I was testing it and it helped me made this bracked in just a few minutes:

And it is a live bracket, updated every one minute (at least they say so). We can easily submit the scores and the bracket will be automatically updated. It's free and very convenient .
