We used it in Boston and it was amazing, extremely useful for a small team like us that don't have enough people to run around checking for matches.
We tried using it from our pits in Archimedes and, even though we could connect to the network, the site would never open. Quite a shame, especially considering we had an even smaller group in a much bigger venue.
Anyway, the service is great and I'd like to thank your team for putting it up!
