The one thing that prevents me from using Challonge only as my main bracket program is the lack of seeding options. There is no way to seed people by location which is what most people are concerned about in brackets since people from the same location should be equally separated in the bracket. There is no way to only seed a set number of players. Instead if you do that it will put everyone in order from 1 to whatever number of players are in the tournament. There is no way of combining seeding methods i.e. skill and location. These are things that really need to be added to Challonge. Give us a way to seed players by location. Give us the ability to seed a set number of players. Give us the ability to seed players and separate the rest by location. All of this would make Challonge the absolute best bracket program. There are some programs that allow you to do these things already however they are stand alone programs and don't have full online integration like Challonge does. People want to be able go online and keep updated on tourney results as they happen. Add the additional seeding options with that and Challonge then becomes without a doubt #1, that is unless they aren't added and some of these other programs end up going fully online.
