Save the previous selected type of login in a cookie
If a user likes to login via OpenID, he has to click "Switch to OpenID" first, to get the the right login form. He needs to do this every time he wants to log in, which is avoidable pain.
My suggestion is to save the user's choice in a cookie.
Steffen Kamper pointed out that nobody needs to click on "Switch to OpenID", because you can also just paste your OpenID Identifier to the username field.
This might be right, but then the divisiion between conventional und openid login does not make any sense.
