Does archerage have an official discord channel?
Another question is that does the forum have a ideas corner where you can post ideas about creating a discord server and more, ideas to make the community come together more?
Probably not. They would have made one already if they wanted one as this isn't the first time anyone has asked and they responded in one of the previous posts about it. I doubt they want to manage/monitor it.
There is a public one that has pretty much most players in it already and it has the leadership of pretty much all the guilds that do anything.
