Yep, well OpenID is so incredibly poor that we're switching to proper logins when we release the new version of our exchange software.
please don't remove support for openid! if myopenid.com is down then it's really easy to set up an open id at a different provider, and open id is so much more flexible/secure than having a logon with a separate password, risk of password database compromise, and no support for two factor authentication (which I use with Verisign PIP).
Please don't remove support for openid!

Sorry but OpenID really does comprise a majority of our support tickets. And people blame us when google changes their OpenID or MyOpenID goes down, they login and have 0 funds. Nearly always people think we've stolen their funds or made a mistake.
