you seems not understanding about integration, I already answered this in my emails:
Integrated means they use the same mysql database,
single user registration, single user login, but each product
has to be installed under different folder, and each
product has its own admin center.
Again, each product has its own Admin center whatever products are integrated or not.
Of course you can insert links from one product to the other in the top navigation, the same for example as on this website
www.mehtag.com , it has all products, customization of the layout is only limited to your imagination, it is all html customization.
