This article argues that from a Group-analytic perspective, the communication dynamics of the Internet are similar to those of any large group. Personal experiences are recounted, showing how the Internet can enable a large group of 450 members to function effectively. Drawing on Kreeger's seminal work on the large group, comparison is made between the `Internet forum' and the extended matrix, questioning Foulkes's scepticism as to the possibility of ever realizing a healthy, functioning large group. The writer looks towards the increasing use and applications of the Internet as one of the most important contemporary issues in group analysis.
