This article presents the case study of a cooperative Web-learning environment--SOCRATES--to foster barrier-free learning on the Web. While the growth of the Internet was exponential in the last years, still many communities don't benefit from Web-learning technology due to improper tools and constricted communication processes. These problems increase when developing applications for communities of people with special needs. SOCRATES supports a community of learning comprising patients suffering from aphasia (aphasics), therapists, researchers on linguistics, and system developers. Aphasics can improve their conversation skills with a specially designed talk/chat tool, while therapists and linguistic researchers can monitor conversations from automatically generated transcripts. Aphasics in remote areas using SOCRATES are now able to communicate freely among each other without being afraid that they might get lost in rapid conversation in a distributed privacy protecting virtual community.
