This site now uses OpenID
If you want to comment... be a URL
To avoid comment spam and bypass the somewhat un-intuitive anonymous comment UI in Plone (Tom, Kai and co - how's that new commenting framework coming along?), I've disabled anonymous commenting but enabled OpenID.
You can log in and comment on posts via OpenID. If you don't have an OpenID account, you can get one from http://www.myopenid.com. This is pretty painless, and you only have to do it once to use OpenID on any number of sites.
