Just adding to the conversation: you have to have an Ubuntu One account to
register in the ubuntu forums now:

"In order to improve login security, Ubuntu Forums now only accepts login via
Ubuntu One single sign on at https://login.ubuntu.com. You cannot login via
other SSO providers. Neither can you login from your Launchpad account, which
was an option prior to a major upgrade to the forum software in February
2013."
It seems what they are doing is, you have to have Ubuntu One to login into
everything Canonical. This kind of centralization may make some sense to
their security team, but for users it isn't.
