Dear Listmembers. As a non American I am unaware of the differences (philosophical and othewise) between the multiplicity of national level PD organisations in the US. Could someone please enlighten me. I would also be interested to learn something about the historical reasons for the split(s). Thanks Dennis. ************************************************* Dennis Greene 48/10 [log in to unmask] http://members.networx.net.au/~dennisg/ **************************************************
