"EMC2 is currently under maintenance or experiencing wallet/network issues. Deposits and withdrawals will remain disabled until a solution is found, which may require an update from the EMC2 team. Any updates must be tested and audited before enabling."
Goes down?
Right?

Where did you got this information ? Its better to mention the source of information. Because without source of information you are just spreading false news on EMC2 community !
I'm not the original poster of this info, but I can tell you that's what it says when you go to the EMC2 buy/sell page on Poloniex. You can't transfer EMC2 in or out due to "wallet issues", so all EMC2 wallets are locked on Poloniex and I guess other exchanges too, although Bittrex shows no errors right now.
Either way, the error on Poloniex makes me unsure of transferring EMC2 to an exchange until I hear more news.
Poloniex has disabled depo/with for every coin that was forked. It's standard procedure. Once they clear everything, it will be enabled again.
Their agility is infamous, though...
