As some of you may already know, we have found a website for generating tourney trees (or 'brackets' as some of you may call them). It sure beats trying to type out the tourney trees manually!
For the information of all tournament hosts, and for all others who are interested, the website is http://challonge.com/
After signing up or signing in, you list your participants and they do all of the work for you. It randomly selects match-ups by giving each participant a random number. It then generates the tourney tree, and gives you the URL at which your tourney tree is located. You can then use this in your topics, together with the Image Code:
[img]INSERT URL HERE[/img]
Once the battles have taken place, the winners can be selected and the tourney tree is updated.
Personally, I like the style of the tourney trees which this website generates, though as always, we are open to additional suggestions in case anyone else knows of a better website to use.
