Student learners show a lot of intense concentration in Triangle Communication's Basic Internet and Email class presented at the Harlem Library last week. Library Director Colleen Brommer said she was expecting a good turnout and the Triangle employees who taught the course were pleased with the number who attended the class. Plans are to offer the rest of the three part series of computer classes, based on interest expressed by the attendees, in the near future. Dates for the additional classes will be announced shortly.
