It takes a bit of time to setup, but once you get into the habit of distributing EP and GP, it's a fairly simple system. The one thing that is highly beneficial is to keep an account on that website and update it with your rankings after every raid. Get any other officers you have to do the same.
If you're going to be using a "points" system for loot distribution, being able to track it is a very handy tool. It lets you see who picked up upgrades, and who is actually making use of those pieces of gear.
