I'll admit that there have been a few threads I haven't posted to specifically because I don't want a record that I've ever been there. (Yah, I know there might be records anyway--I've notice that the board seems to know where I left off when I hit "go to last unread post", but I'm hoping that info is purged after a few days, when it's no longer needed for its purpose. If you post, your post is definitely there for forever.)
