In a lot of the tournaments we run, we will try and "rig" the tournament so that players who normally practice against each other, or play each other frequently, don't have to be matched up. (Allow for new competition, etc.)

Something that would make this really easy, is that after the seeding process is done and you get to view the preview; if you could just drag and drop players to different spots. This would allow you to resolve the situation I previously described, as well as still see the seeds and make it fair.

I am hosting a tournament where I had 99 Participants. One of the participants sent bulk messages (approximately 15 messages) to all other participants promoting her games page through our tournament. The messages also asked people for their User Names, email address and passwords so she can sign up for them.

I spoke with another games page administrator who confirmed this same person did the same thing to his page.

It would be ideal if we have an option that only the host of the tournament can send emails to participants, this would prevent people spamming other players.

I'd like to be able to use Challonge for three-player games (with different options i.e., one winner per game or points distributed based on finishing order, etc.)

I think it would help to allow users to specify how many round robins to have in a tournament. I'm going to be running tournaments that require a double round robin format, so this would be a great help.

If there are less courts then games to play. Should help to manage a tournament, where more games had to be played then courts are available an teams have waiting positions. Just to give an overview of the number of rounds to play, number of games for each team, etc.

My brackets are set up with the same basic group each time. I have to save my member's challonge info somewhere and plug it in each time. I'd love to be able to save these individuals to a friend's list associated with my account so I can easily add them to any future brackets.

While the ads aren't particularly intrusive on Challonge, I'd like an option to remove them from the Challonge website for an extra fee. If nothing else, it would be a nice way for users to support Challonge that don't need a module for their own site.

You definitely need to add a feature that allows users to re-seed the bracket once the first round is completed. A few pro leagues use this and it would be a useful addition to brackets.

I run a League of Legends tournament every month and would like an option to allow captains to include team member summoner names. To avoid "ringers", and allow teams to scout each other before games, these would lock for users at a given date/time but still be editable by the tournament organizer.

Your online website is awesome, especially your simple-yet-effective Swiss Round generator, but I would like to be able to use it if I do not have access to the Internet.

An offline version for PCs/laptops and/or a cellphone app (Google Android pregerred) would probably help those without access to the Internet greatly.

Now you have total score and then tie-break score. there are other possibilitys.

Would be great to force players to confirm that they will actually play, not just 'register and forget'. Implement adding stage between register and publishing tournament where players have to enter site and click some kinda 'I confirm that I will play' button :)

The ability to integrate challonge tournaments with wordpress so users can sign up and report using there account on a wordpress blog/site.

Is there any way a second tie breaker could be added to the swiss format?
First divide even scores by the entrant's they won against's total wins like it already is then break up the scores that are still tied after that by using total wins of the entrants they lost against?

I would like to use this program to host tournaments for a game I run but currently we still end up with ties even with the current tiebreaker.

Add another tournament type. Ladder Tournaments are a seeded bracket in which seed 1 plays 2, 3 plays 4, and so on. The winner moves up a position and the loser moves down. It is run for X amount of rounds and places are determined by which position each player finishes after all round have been completed.
