I've made this journal friends only simply because it seemed like a smart thing to do given the hassles other friends have encountered from having public posts.
If you're thinking of making your journal friends only try
http://james.is.never.wrong.nu/code/hidejournal/ it hid all of mine in like 5 minutes...granted i'm not that prolific.
anyway
if you want to be added to my friends list just send me an email or some such. most likely i'll add you unless you're someone i actually know and have talked smack about in the journal. ;)
