How can I get an OpenID Identifier?
An increasing number of existing sites are adding OpenID identity services alongside their existing facilities, so you may have an OpenID identifier already without realising it. All users of LiveJournal, TypeKey, WikiTravel, GreatestJournal and Vox — among others — already have OpenID identifiers. There are also several organisations which provide dedicated OpenID services rather than bundling them with existing services. These public OpenID providers operate independently of any central controlling authority, so you can select a service which suits your needs; your identifier will still work across the spectrum of sites accepting OpenID sign-in.
