This plug-in is an OpenID server. Specifically, it's an Identifier and an Identity Provider. OpenID (http://openid.net/) is a distributed authentication protocol, ie a single sign on platform, that uses URLs as identifiers. If you have a PyBlosxom site, this plugin allows you to login anywhere that accepts OpenID.
This plugin also implements the Simple Registration Extension, which lets you optionally provide your name, email address, and other information automatically to sites that you log into with OpenID.
