[vtkusers] [vtk-developers] I 'm not sure if my mails be sent to the vtk users or not

[Berk Geveci]

Hi Ali,

Please stop cross-posting your question to the vtk-developers list.
This mailing list is for those that develop VTK itself and not for
users of VTK. Your posts have been received by the vtk-users list and
some of them received plenty of answers.

Best,
-berk
