Thanks Tony and Dieter for replying. Zope is a great product. ZPatterns and LoginManager are great products too. I use ZPatterns and LoginManager. Thanks to http://www.zope.org/Members/BwanaZulia/zpatterns_install and other links Basic applicatiuon development require a lot of knowledge to setup. This will deter people from switching to zope from other platforms(for instance from PHP to zope). They also have access to free products and plugins from their user community. In order to develop PHP applications newbies just have to learn PHP programming. In Zope we have to learn Zope + Python + DTML + external methods to fully appriciate an application like ZPatterns and LoginManager. In oder to show that Zope means business when come to solid application development, certain thing must be built-in into Zope. One of them is form based login/logout system instead of HTTP authentication. I am new to zope but you have to understand that a lot of people are new to zope (and have a steep learning curve). Hope more people reply. Thank you. Mohan.
