This chapter examines how environmentalists' attitudes towards inclusion are translated into their use of computer-mediated communication (CMC). It outlines the importance of inclusiveness to environmentalists. The chapter demonstrates that the interviewees' attitudes, while reflecting a desire for inclusion, lead to practices of exclusion. It explores the ways in which environmental activists have secured access to the technologies, how they have tackled any problems encountered and, additionally, whether CMC use has altered organisational forms. In addition to acknowledging and attempting to resolve the access problems they faced, activists employed CMC as a way to create new avenues of access to information they wanted to distribute. Access can be mediated by membership to a group and CMC use could alter the functions and structure of an organisation. The chapter further considers the effects of organisational form on CMC use, and the effects of CMC on organisational forms.
