on *:OPEN:?:*: { msg $nick You are number $query(0) on my pm reply list. }
[edit]
Of course, # is replaced by the number of currently pending pm's that I have coming in.
The above is close, it tells the user what pm window number they are, it cant take into account other pm windows you migth open yourself as it cant tell the difference between no pending and pending ones, (you could do that in scripts but then whats a non pending one, one u have seen?, one u have answered?, one u have finished with?)
