TrinityCore is an MMORPG framework that's built using C++, and using a back-end of MySQL for the DB content. Trinity was at one point a merger of MaNGOS with many patches submitted by users, that is no longer the case. Trinity is an individual project with a diverse development team, We love to hear from our users too, whether you want to give words of encouragment or if you have code for us to merge into the repo (please file a pull request if you do, we love it when users contribute :) ). Trinity has been cleaned up a lot, and will continue to be cleaned up and optimized over time. Please help us by posting issues, patches, and enhancement suggestions on the tracker.
