Hi Petar, I suppose after a couple of headaches you may want to try out zope as well ;) http://www.zope.org/ It saves you from most of the work with forms and many more. Hard to grasp the principe of operation at first but profitable at the end. HTH Tino Petar Karafezov wrote: > > Hello all - > > I am running Apache/1.3.14 (Unix) mod_python/2.7.2 Python/2.0.
