I will enable threadmarks for Archivists, mods, etc, today. I might go as far as to give them to Early Adopters too, but it's probably worth waiting for the system to be tried out a bit first.
I'm also probably going to make an 'ongoing auditions' widget sometime within the next few days, as part of my effort to slowly expand the value of this forum as a general place for vtuber info as a whole.
