Subportal in www.sustAINABLEINCUBATOR.ORG. [login to view URL] already exist and works (the ecommerce virtue mart doesn't work and we dispublished it) what I want is creating a subportal identical to [login to view URL] inside www.sustainableincubator. this subportal would be called arttherapy ([login to view URL]) it would be identical; yust to change some colours (red and blu) and to put some photographs above in the home page as in [login to view URL] what about virtue mart in the subportal? is it possible to dispublish it? or easy to make it work?
