I am pretty new to this quitting stuff myself but I have a decent handle on telling when someone has the fortitude to really quit and when they are just going to post roll for a week, not get involved in the forum and just go away in 7 days.
Punkin has got some serious quit in him, heck, they have a pretty strong looking group.
Plus, with a name like Punkin...I just kind of wanna hug him.... :o
