The sites below were all designed by the same company and use some article script. I'd assume it is an off-the-shelf package since they seem to be using other third party stuff in there development, like the project7 menus and what not.

Does anyone know what article script they may be using? If not, can you suggest an article management script that does the same thing? vBulletin forum integration is a must, too, as these sites all do it.
