Here is how to set your RSS news reader to read Protected (Friends-Only) posts.
I mention this because I had some trouble getting this to work with the available instructions out there.
This is tested on RSS Bandit.
Create a new feed entry with a URL like this: http://www.livejournal.com/users/YourFriend’sUsername/data/rss?auth=digest
(replace “YourFriend’sUsername” with… I’ll let you guess)
Go to the Authentication tab and type in your Livejournal username and password.
Done :-) You can now use that feed entry to read your friend’s posts.
I read in several places that you should do this:
(replace Username, Password and YourFriend’sUsername)
I haven’t found this to work.
