Haowei Lee, a Fedora ambassador from China, has approached me about helping him get a "verified" status for an account on Sina's microblogging site -- essentially the Chinese version of Twitter or Identi.ca. I'm assuming this has trademark implications, so I'm bringing it up here for your consideration.
You can see Haowei's request at http://lists.fedoraproject.org/pipermail/marketing/2011-April/013856.html
