The best thing about this is that it can be used in any game, even when not using Ludum Dare! It's also really easy to use once you understand how the system works. You have to manually create each event (and I do mean MANUALLY) so if your team has lots of events/events with many people or just some large ones, then you'll need more time for setup than others will require. But overall it's very good at what it does and worth taking advantage of while it lasts. Scheduling tournaments across multiple games without having to worry about them being out-of-sync.
