So, I've had many annoying whines^H^H^H^H^H^H^H^H^H^H welcome requests from readers in the past for OpenID authentication for posting comments. I didn't implement this for a long time. I told people it was because I was worried about spam but really it's because I'm freaking lazy.
I tried to enable this a while back with the standard Wordpress OpenID plugin, but it didn't seem to work (as many of you have noticed). I left it in this broken state for months, again because I am freaking lazy.
Today, because I'll do almost anything to avoid writing an FWN beat, I actually got this implemented in a way that works, using a different plugin - this one. It uses an external authentication intermediary called RPX. This is slightly worrying, but I did look around a bit and read the license terms carefully and they don't seem to be evil. Please do let me know if you know anything to the contrary.
The good bit is that it works - I tested - and it allows login with Yahoo, AOL and Google accounts as well as OpenID. So that should make it easier for people to comment in future. YOU'RE WELCOME! You can also still login with your existing account on my blog, if you like - there's a little link down the bottom of the RPX login screen for that.
I reserve the right to disable this again if it causes me to get spam comments.
