I sent in a ticket too but I am not qualified to make an official statement about current XCR status.  They had trading on April 11 but zero XCR trading in the past 24 to 36 hours.  It seems that there is ongoing miscommunication that needs to be addressed - 15 BTC on the buy side vanished with the freeze announcement and hasn't come back.  With Bter closing and Cryptsy stuck on an old wallet, Poloniex is the ONLY fully functioning exchange to bring in new Crypti members.  I understand not worrying about price during development.  Still, smooth trading on Polo at SOME market price is critical for XCR to be viewed as a healthy coin.  Trading at Poloniex should be monitored and nurtured and watered like a rose in the desert until we branch out to other exchanges.
