Official Produce 101 Thread

So I'm compiling all of the information on Produce 101 here so people can keep track of what is going on and understand what is happening.

It is a large-scale project in which the public "produces" a unit girl group by choosing members from a pool of 101 trainees from 46 entertainment companies as well as the group's concept, debut song, and group name. It was revealed that the unit girl group from Produce 101 with 11 members will debut on April 3, 2016 under YMC Entertainment. From what is known the public will vote and choose who the final 11 members will be.
