* Go to someone's LJ page
* Click on the Reply link
* You should see the user picture on the top, i.e. "Tony says... @ 2001-02-02.. etc" When you hoover your mouse pointer over "Tony", it should show my LJ URL. But in this case, it doesn't work like that. It's showing the URL of the person's message I'm replying to.
Did I find something that you never knew?
