Hi!
I had some questions when I read pooma tutorials. Now as this mailing 
list do exist I'll ask one of them.

    How a flat metal(perfect conductor as I suppose) sheet could have a 
_potential distribution_? It has only the charge distribution,
but the electric potential is constant on the conducting surface in 
(quasi)static case.

Cheers,
    Roman.
