I was riding high with PD, up to 0.05 profit, then I crashed down to -0.04 profit and decided that I'd better quit.  Haven't played in a while.  I think that lifetime profit/loss stat might be too much of a reality check.  I know it's kept me from putting in more money once I saw how far behind I was.  On the other hand, it's very open and honest of PD to show us this so easily.
