In short, organize tournements with very little overhead, let players compete among themselves and see who comes out on top.

Technical Description:

This mod creates a set of ladders stored on the server in CSV and allows players to self manage these ladders via text commands.

Purpose:

Allows players to manage and run simple ladder tournements without needing a third player to manage and track the whole thing. I've always been frustrated by the difficulty organizing a competition in minecraft servers. All the players have to be online with the referee at the right times, people always asking who is up now, who is on top, whats my score, etc.

Mainly the trouble is timezones and overhead though. If you want a competition there's a good chance some of them aren't online when you are. This mod is made to allow players to semi manage their own tournement, so that all you need online are the competitors and the two of them can register a win or loss on their own.

If they don't agree of course that's different, and you will still have to mediate conflicts.

Features:

Planned for V1:

Any player can create a tournement
Players can list active tournements and players can add themselves to ones they like.
Basic single ladder tournements will be supported.
New players are placed at the bottom of a ladder, and can challenge any player within 5 places above them.
The mod will then remind both players that they have a challenge to fight.
After the two compete, the either player can register the win or loss and a score.*
The other player is reminded that they need to confirm/deny a win/loss
Disagreements result in no one moving places
An agreed win by the challenger will allow them to move up to one rank above the one they challenged.
Maximum of 100 ladders of 100 players each supported
The creator of a ladder can delete it at any time, and players can remove themselves at any time

A mod by Synaps4. I can provide source code upon request, but I'd like to be attributed. Collaborations are most welcome.

Future plans, no particular order:

Complete the mod, still only about 50% completed
Add a configuration file support for the expiration time of ladders, the number of places above onesself that a player can challenge
Add expiration time for old ladders and old challenges
Add support for other tournement types other than ladder such as single and double elimination knockout, and round robin
Add ingame admin management
Add support for a configured referee who owns scoring and points management for the tournement
