Spheredev has been down. The forums were ultra-spammed a year ago, and now they take up an aweful of space on deservedlyso's disks. Like, at the moment 99.99% of the space taken up by Spheredev is spam from one year (it was a war, an epic war). Kamatsu has been talking about restarting the forums someday soon, and I think that day is looming ever closer.
Edit: I've talked with Kamatsu, Spheredev is back.
