According to an article in the Tibetan Nuns Project newsletter (Fall 2012), a special Gelongma Research Committee was formed in Dharmasala to do conclusive research on the issue of full ordination for nuns. The committee began its work in August 1 and was to conclude by early November. Samdhong Rinpoche presided over a committee organized by the Department of Religion and Culture of the Tibetan government in exile. More information about the meeting and a brief background about the issue can be found on phayul.com.
I checked the Tibetan Nuns Project website but didn’t find any information regarding the outcome of the meeting. If anyone has more information, please share!
