So is it possible now to do something with your remaining existing TME coins on Novaexchange?  Is there a contact you can send a purchase history request to to prove you bought them before the problems began occurring?  Is it a good idea to transfer them off novaexchange into myetherwallet or metamask or the like or would it be better to leave them on the exchange to prove you had them at one point?

From the looks of it, you can't buy any TME currently on Novaexchange (+ is greyed out), so I'm not sure where the worry about people purchasing cheap TME and exchanging them for ELIX is coming from.
