Hey there,
Thanks for this plugin :)
while optimising a site noticed that the sidebar login plugin is trying to load a gif - even though the openid plugin is not present - and wasting a bit of server resource in the process:
#openid_field{background-image:url(/wp-content/plugins/openid/f/openid.gif);background-position:3px 50%;background-repeat:no-repeat;padding-left:21px !important}.widget_wp_sidebarlogin
CSS may need a tweak - can't find any options for OpenID on the admin although I could see how the two plugins could obviously work together.
cheers
