This hack screws up the Subject line when the topic-starter edits the post.
First edit it inserts | between each character. Second time it turns it into a string of asll available characters ("|A|B|C|", "|1|2|3| and so on).
Dont know how or why...it's just one little piece of code.
Oh, and when I try to uninstall it by working backwards, it corrupts the page cuz the line is off somehow.
Other than that, though, it does what it's supposed to.
