I run a Pokemon gaming website. I am looking for someone to create an addon that will assign a rating to each user and create a ladder system to rank all users based on rating. The end result will be something very similar to http://pokemonshowdown.com/ladder - but customized for my xenforo community. If someone can point me to the direction of a preexisting addon, that will be much appreciated. If there are any developers who would be interested in working on the creation/customization of this addon please let me know. Thank you.
