Ha! Turnover...you forgot to move your turnmarker... !
Oh good old times.Oh precious moments.

These days are over, only thing that happens now if you forget
to click on the turnmarker your opponent might get anxious about your turn taking so long though you moved all of your teams players.

But why a turnover only because you forgot to move that little
cardboardsquare...?
Everyone who played several games on the tabletop (yes there is a world outside the www.) knows why:"Hey dude what turn do we have?". -Pause- "What do you mean what turn?" "Well my marker says 5th turn and yours 3rd you forgot at least 2 times
to move it and if I forgot mine too we´ll have a long half."

That´s was the resulted of forgetting to move your turmarker
was.

The Javabowl client prevents these mistakes perfectly by not
doing anything until you ended your turn properly( or by any
other kind of turnovers ).

But it´s less fun...
