Abstract. In this paper we introduce an instant online community (IOC) solution as an add-on for existing websites. The IOC enables social interaction between the main content provider and visitors of one or more websites. We present the successful application of the sixgroups.com Livecommunity in the context of a joint conference to support communication between organizers and attendees, and attendees amongst each others. All stakeholders are supported throughout the conference, from preparation until follow-up. Yet, the main focus lies in accompanying them while they are attending the conference. The lessons learned and conclusions from this application are discussed, as well as the steps to be taken in improving the sixgroups.com Livecommunity.
