This paper provides an overview of the variables critical to the success of an Internet site design. The site under development represents one aspect of dissemination for the Modeling Instruction with Modern Information and Communications Technologies: the MIMIC Project, a U.S. Department of Education Capacity Building Grant. The site focuses on materials useful to the integration of technology into pre-service teacher education programs. Critical to the success of this Internet site is the development environment created to support participant collaboration. This development environment evolved from a variety of approaches established to encourage student and faculty involvement. Assembling the design team is discussed, including the following characteristics of "hot groups": task obsession becomes a state of mind; "we" dominates "I"; the organizational structure is more egalitarian than hierarchical; members do multiple jobs; and the groups are small. The following conditions for an appropriate environment for the design of the Internet site are described: competence; a shared goal; mutual respect, tolerance, and trust; representation; communication; and responsibility.
