You will just need to get a username if you don't have one already at LJ (it's free) and then post a little note in my comments section; or let me know here. I have the journal set as "friends only" because I post pictures of us - I'd love to add you guys as friends though!
I like Blogspot, it's part of Google now, and now that it's changed to Google, it's a lot easier to use. I haven't used other blogs before though, so I don't have much to compare it to. You can blog on Myspace too. They are both free.
