I’ve added OpenID authentication here, thanks t' th' excellent WordPress OpenID Plugin from VerseLogic. If ye already have an OpenID identity, ye can now use it when commentin' here, and yer name will be flagged with an icon t' signify that yer identity were bein' confirmed. If ye don’t already have one, ye can sign up with any o' several OpenID providers. I use MyOpenId.com fer mine. Yaaarrrrr!
If ye want t' read more about what OpenID is about, try startin' with Simon Willison’s excellent post, How t' turn yer blog into an OpenID. Fire the cannons, pass the grog! For th' flip side, learn what OpenID is not: An OpenID is not an account!
