There are few software options available to assign games. Arbiter seems to be the most used platform.
Arbiter is more than just where you see your games. Partner information is in there, as well as addresses of the venue you'll work, what your pay is, and much more. It is also a way for you to COMMUNICATE with your assignor(s), and the most important way you can communicate, is through your blocks.
There are quite a few pieces to the Arbiter puzzle. We will continue to create and provide content to help you navigate this application.
