Abstract
Eppler and Walker explore the interpersonal dynamics of two sisters communicating via e-mail correspondence. Using a case study and qualitative approach, data were collected from two sisters through the use of a semi-structured interview, creation of an eco-map, and completion of a timeline/calendar. The participants are Caucasian sisters in their mid-twenties who have lived in different states for four years. Systemic relationship factors such as space, time, and energy are examined. Findings indicate that e-mail messages within the family eco-system have the potential to sustain and foster commitment, trust, and support. The flexibility of time in computer mediated correspondence is a powerful component in maintaining and nurturing the sister-sister bond. E-mail is discussed as a modern approach for promoting supportive sister-sister relationships.
