Addition to 'Tell a friend' feature
Short, concise description of the idea
Add the possibility to tell non-LJ-using friends about non-public journal entries
Full description of the idea
Right now, you can tell people you know but who don't have an LJ account about non-public entries, but they can't read them because of the security setting. Neither could they comment on them. I suggest a system that enables such people to read and comment on such entries. To mind comes a system like Support's auth codes. Someone who receives such a mail can then click on the authorized link and be able to read and comment (as Anonymous, perhaps with a marker that this was an authorized viewer) on the entry. Obviously for security reasons, such mails for friends and private entries could only be sent by the journal owner itself. A journal entry that hasn't been sent to someone shouldn't have an auth code and therefore shouldn't be readable through 'auth code guessing'.
