The open format program yielded great crowd participation. To start the program, prospective students were asked to introduce themselves and state their intended area of study. Prospective students listed Business, Engineering and Communications among the potential areas of study. After the brief introductions, Korey Hawkins provided general information on the recruitment process and the current state of affairs at Morehouse.

Many of my classes are an open format style. "Open format" means that you contact me, we discuss what you want to do, and I help you reach that goal. Sometimes that includes doing extensive research on your subject, suggesting a more artistic composition, or designing your pattern. Sometimes it means that you're a beginner and I help you get started, with beginner-level projects and suggestions about tools and other related subjects. Beginners are welcome in all open format classes, and private classes are available from time to time.

Support groups usually have a set meeting time (generally weekly or monthly), and an open format. Open format means that the groups are ongoing, and members have the option of attending when it is convenient for them. This is in contrast to other types of structured treatment or psycho-educational groups that may meet for a certain number of sessions, with the expectation that participants attend every meeting. The open format allows members to feel some degree of anonymity, and to participate as they are comfortable. For some people, simply attending meetings and listening to the experiences of others can be helpful.
