Shoutbox is rarely used and discord is far faster. It also takes into account the 'randomness' of such a situation. I'm online now and even though I can go in the next 10 minutes, I can also stay for 2 hours if need be. I'm not exactly going to say that I'm free every day from 20-00. Life's far too spontaneous for that.
And what if I'm free from 17:00.
Also, it's going to be far too much effort for someone to coordinate and calculate when everyone is one, especially with all the different time zones.
Trust me, some of the best events happened spontaneously, a discord server is best. (Or maybe even better, ask Nova to make a channel on the already existing discord server)
