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 think you're missing one of the points of OpenID - it's a decentralized system that doesn't have a "master list" - anyone can setup their own OpenID server. If software is built such that it follows the OpenID specifications, it won't need to know the URL of the server ahead of time.
