xochat.org is trundling along. Dying about once a week. It sometimes takes me a while to notice this. Until it is moved to a real server, which is just a question of how long it takes to prod along my volunteer sys admin to move it to a new donated server, it is not going to be very reliable. Basically, this means it is fine for getting a general idea of how collaboration works on the XO, but not useful for getting any sense of the reliability or performance of said collaboration.
