I keep a journal, well, really it's called a blog. You can register for a free one on a number of different sites. Just google "free blog" or "free weblog" and a few sites will come up. On most of the sites yo ucan determine how you want your blog to look, who can comment, whether or not you want to password-protect a post. (If you password protect the post, no one can see it without knowing the password). Hope this helps!
Take Care,
