I haven't been on ubuntuforums.org for ages, but I came across a thread from a search. Annoyingly, the forums require to be logged in to view images! So I tried to login.
I was looking for a login field to enter my OpenID URL (https://launchpad.net/~james.r.haigh), but I couldn't find anything. I'm pretty sure there used to be something obvious like ‘Login via OpenID’.
I tried entering my URL in the username field, but as expected it didn't work.
