Rainbow Six: the proposal now has four interested players so it will be greenlit as soon as the details are thoroughly discussed.
Space Pirates: the proposal could become an independent sim or be merged into a reactivated Umbra. Discussion is currently up.
An Elegy of Iron and Blood: the proposal will become a new sim very soon.
Wing Commander Gemini Sector 2.0: roll call in progress. I hope it will be approved because it sounds really interesting.
Soldiers of the End A(nother) Mass Effect Sim: currently no interested players (a pity)
Steampunk sim (still unnamed): Roll call in progress.
