Mr Sullivan, I installed the hack and it seems to work quite well!

We are already testing it on my test board (if you remember the URL, come by and check it out).
Just a couple of things to note: there are no graphics for the "messages read" feature, so if you install it, you will need to create your own graphics (no biggie!).
I'm not sure the "message read" feature is working. I still get the same graphic whether or not it is read. Or does it go by the amount of time the cookies are set for?
But so far, so good! I'll keep playing and let you know if we come up with anything else! Great job, Mr Sullivan!
