I've implemented OpenID on my website but I'm having a hard time finding a list of OpenID Provider URLs. I thought this would be easy to find but I've scoured the web and only found a handful, mostly by accident.
Is there a resource that lists available Providers and their authentication URLs?
EDIT: Here are the ones I've found so far. I haven't tried all of them so let me know if any of them are wrong.

I would propose to use the http://code.google.com/p/openid-selector/ library. It has the most used urls + graphics for each site.
It is what stackoverflow uses.
