I emailed about getting a key for the query API awhile back and haven't heard anything. But hard to know if it's even the right email address. At one time I think I offered to help support any ongoing maintenance costs. That offer still stands for whoever hosts in the future, be it Darkcanuck or someone else.
Really? Maintenance costs are what were preventing me from trying to raise another server. Free clouds severely limit resources, and I was thinking in implementing a Ranked Pairs ranking system, which consumes a lot of main memory to calculate in a reasonable time.
Current APS, PL and ELO systems can be implemented with fewer resources in free clouds, but I wasn´t willing to go all the way only to repeat what is already being done in Darkcanuck´s and Skilgannon´s servers.
I'm also willing to pitch in (or purchase) if we need a new RoboRumble server (or App Engine account or whatever).
