jmac.org is back and on linode.com
jmac.org (and gameshelf.jmac.org and appleseed-sc.com) is mostly back up, and should stay that way, because I fully expect Linode to do me right where Tektonic has failed. Please let me know if anything seems amiss; gonna keep the old server running for a little while (at a different name) just in case.
