All I can see online is that March 28th is "Serfs Emancipation Day" in China, the 51st anniversary of the Chinese government's dissolution of the Central Tibetan Administration, the government headed by the Dalai Lama which had ruled Tibet for nearly 400 years. Therefore this is also the 51st anniversary of the Central Tibetan Administration's government in exile.
EDIT: Hmm, my posting history says I posted #2790 on 3/27 and post 2791 on 3/30. I guess I missed it last year.
I was cleaning up my inbox today and after a deleted a PM it sent me to the writing a private message screen with a pull-down list of what looks like all the Wieners. Is this a bug or is this meant to happen?
