 ===== Results =====
-Our activities have been surprisingly enjoyable and productive. Younger researchers, especially, have benefited greatly from the interactive experiences we've fostered. Through feedback surveys, participants are overwhelmingly positive. It is an added bonus that the sessions have consistently produced significant scientific output.
