Hi:
Main net is scheduled to go live this month. Dan Dabek said in an August 6 update that the team would use "the entire time until the last day" as part of the launch. You will need to move your tokens to the Safex wallet in order to convert them. More instructions on that will be provided in the future.

Projects never launch on the exact day. They'll probably take a little longer but it's worth it because they have more time to make it purrrrrr
