Setting up sign-in providers

WordPress can be setup using IDs from other sign-in providers, e.g. Facebook, WindowsID etc. This requires a WordPress plugin and corresponding web service from JanRain. There is now an application registered for RTKCC,

Login for rpx’s site is using the WindowsID.

RPX requires cloud/web service applications for WindowsID and Facebook

WindowsID using, look for service/component RPX Now
Facebook  using a private FB login, should be switched to use a RTKCC Facebook app
