Welcome to the Defrag Conference Groupsite. Groupsites are powered by the CollectiveX platform and combine the best features of discussion forums, email lists, calendars and social networks. They can be setup to be completely private, or public and open. Groupsites even offer dual profile personas… so networking within Groupsites can be primarily professional or social… you decide when you create your Groupsite. Best of all, Groupsites are free to setup and enable you to control your group’s branding, privacy and members.
