I've been trying to logon to Software Engineering via Yahoo OpenID for the last 20 minutes, at the very least 15+ attempts, and it isn't working.
I am brought to a open.login.yahoo.com/openid/yaddayadda
URL that freezes on a black while screen, and that's it.
I did manage to get through another Stack Exchange site, which logged me in for all sites, but still, maybe it is something that needs to be looked into.
