Of course, I'd still like to pay you. But not sure how much to send or where to send it.

Huh, haven't given it a lot of thought since I rarely do these things professionally. Is $49 too much? It will include a stats area with any stats that you may like to have, displayed as absolute values and horizontal bars styled with CSS, it will be completely integrated in MLF, and I will keep it updated for the future versions. I made sure that it follows the MLF philosophy, menaing it will be light, use the smarty template...the author may want to add this to the default distribution maybe...
I'll send you the files which display the list of top posters so you can check it out before I go on and add other stats. The default code is not changed except for the addition of the stats menu link.
