The login page for all SE sites was revised a while ago and the self-hosted OpenID form field was hidden behind an ajaxy mouseclick.
I use my own endpoint on a personal domain to login (christopher.woods.name) and I'm sure others do the same -- it wouldn't compromise the page design if the OpenID form field was displayed all the time, with the buttons for third party OpenID servers now on the site it disambiguates the OpenID-specific form fields. Can the text field for custom OpenID URLs be reincluded on the login page without having to reveal it via an extra mouseclick?
It's a small request, but one which would make me far less frustrated every time I log in. :-)
