The blog has been upgraded to WordPress 2.0.5: Ronan. This is an incremental upgrade, so I do not anticipate any major issues. So many people are doing this upgrade today that the instructions page for upgrades on the WordPress Codex cannot be accessed. Good thing I remember the drill from last time.
Plugins will be coming online as I test them.
[Update: 3:00pm] All my plugins are running; I see no problems. In addition to upgrading WordPress, I installed the latest version of the excellent anti-spam system Spam Karma 2.
PS. For the record, free open source software remains the best thing since antibiotics.
