I'd absolutely be for switching to Discord. I use it all the time now, it's easier to use imo (and you can set different channels for different things which is nice, like we could still have an 18+ one if that's still a thing). And you can do voice chat and stuff there too.
Skype completely overwrote my existing account 'cause they changed it from "Skype account that happened to be created with a hotmail email" to "Microsoft Skype account", meaning it's completely integrated with my email and everything - and I have none of my old contact information. So that's why I've been gone from the group chat for a while, 'cause I can't get to it anymore. :/ So yeah, that's another plus with Discord, no worrying about meddling like that.
