I must have seen at least three threads this week, and plenty more before that from users who have renamed their House icon and now are panicking because all their files are missing. The name next to your house icon is the name of your home directory. If you change it, and then log back into your account it notices you no longer have a home directory for that account and creates a new blank one. This is why it seems as though all your files of gone. In fact they are still there, just in the renamed folder in /users/. To get your files back, use this: http://docs.info.apple.com/article.html?artnum=107854 If you really want to rename your home folder name, use this: http://docs.info.apple.com/article.html?artnum=106824 By the way, why the heck does OSX allow you to change this name without any warning of what might happen when you do?
