The CallSheet, OMPA's monthly newsletter, keeps members informed about important industry news and events. OMPA encourages its members to use the CallSheet as a forum to exchange ideas and promote themselves.

Every month, members submit industry-related press releases to the CallSheet's "Members At Large" section and use the classified section to publicize their upcoming events and business opportunities. OMPA must receive press releases and listings before the 15th of each month via e-mail or regular snail mail.
