I only joined the SHL discord when I saw the PT.
I think Discord is a great way to get to know people and I think team discords do that very good. The SHL discord seemes kind of dead for at first glance, as rhe Commissioner I would clean up the channels. Having a General channel for shl and smjhl related discussion, a NHL/Hockey channel for hockey talk, a meme channel cause people seem to enjoy that, a off topic channel for everything else and then a announcement channel for importand announments which would be viewable for all bot only HO and GMs can make announcements.
I personally don't really see a large need for a SHL discord as the Team discords and rookie discords great. What I belive it provides/could provide is getting to know people that is not on your team or in your rookie class. The site is a great place for more in depth discussion and discord feels like a more shallow and meme prone environment. Which can be fun at times just not all the time.
