Could really use an extra paragraph in it, something like this perhaps:
Some web-browsers offer a feature where they will remember passwords for you when you log in to various sites. Never use this feature when logging in to LiveJournal. If you find later on that your private computer becomes shared, it is much easier to change your LiveJournal settings than to reconfigure your web-browser. If you have used this future in the past and need to stop using it, the easiest way to secure your account is to change your password at http://www.livejournal.com/changepassword.bml
