Having physical access to a community and having a sense of community is not always an easy option for Third Culture Kids (TCKs) who live in a culture other than their parents’ native cultures such as missionary families and government and non-governmental agency workers located in various countries around the world. One TCK stakeholder (a co-author) decided to practice creating community and research by conducting a participatory action research project with a goal of engaging a subgroup of TCKs called missionary kids (MKs) to meet online and to create a sense of community. Participants (N = 20) ages 16 to 40 joined website discussions and influenced how the website was developed and operated in addition to allowing their online postings to be used as data to study sense of community among MKs. Data were analyzed using McMillan and Chavis’s (1986) four dimensions of sense of community: membership, bi-directional influence, needs fulfillment, and shared emotional connection. Findings show that MKs connected through the Internet, developed a sense of community, influenced how the website functioned, took control of online community regulations and norms, and provided social support for one another. The website started in 2004 with two members and in 2011 had 1801 community members. Findings have implications for expanding theories of sense of community and for practices to create and sustain online communities.
