I'm trying to figure out how to tell when someone on my board whom I've sent a PM warning to has read it. Is there a hack or some way that I can have it show when the PM has been read by the user? (Obviously they don't usually send the "read receipt" back on that kind of thing so it's basically worthless to me) Or some kind of notification that it's been read emailed to me? I've searched the forums but didn't come up with anything so forgive me if this has been asked before. Thanks!
