have friends's entries, even locked ones, emailed to you
I wrote a script that will allow you to have your friends entries (even locked ones, as long as you have permission to read them) emailed to you. (this will work on any RSS feed, including those requiring a password, but I wrote it specifically with LiveJournal in mind)
It might be a bit tricky to set up, but I tried to make the "read me" file as easy to follow as possible.
It does require *nix - be it your own box, the server your web site is on, whatever - and command line access.
