Yiming, Many people, including myself, would like to see a standard mechanism for exchanging information between modules. Your idea of discussions attached to products/pictures/etc is a great technique to help build a community. Similarly, a rating engine could be built and attached to various items in other modules. If you search the mail list archive on this topic I think you will learn some of ideas and issues that have been raised in the past. (oops, I just went to sourcForge to give you the URL of the mailist list search page and it has dissapeared. SourceForge says the mail list is not being archived, anyone know what happenned here? http://sourceforge.net/mail/?group_id=66837) Anyway, hopefully we can recover this previous discussion. Since we are now such good friends with DNN, and want to share modules between platforms, does DNN have a mechanism defined for passing info between modules?
