unsubscribe which links (indirectly) to: https://community.plus.net/t5/user/RemoveUserEmailPage/user-id/@@@/mail-message-tracking/IMUWY4D****... (User detail munged). This link takes you to page to remove your Email address from the Profile! Potentially very wrong especially for Newbies? I'm not clear quite what the intention was and therefore where a better landing place would be. Needs a bit of thought, but in the context of the source of the email it could be the same link as above? Possibly needs a 'Help' bubble to explain the context.
Of course I could just be confusing myself in the detail.
