I went to RMA in the early 1990s. My understanding from some staff with whom I used to be close, is that they used to have staff raps facilitated by Dan Earle, Carmen Earle, or in the early days, by Mel Wasserman. I was told that they were intense, that staff would often get nervous about them, and that they were generally thought of as helpful. Dan and Carmen left RAM in the late 1980s and with their leaving, staff-raps stopped.
There also used to be staff-only workshops -- those too had happened during the the first 10 years of RMS's existance -- prior to my going to the school.
Best, M
