OK yesterday I was talking on SL and suddenly after a rather heated discussion with someone, my ability to speak on voice stopped. I still had my dot and I could hear others but couldn't speak myself. Is there some way through scripts, land management, open collar or by other means someone could have purposefully done that to me? My ability to talk did come back after I restarted voice, so it's not an ongoing concern but I wondered if my suspicions have any merit.
