Hi! I have created a chatroom for discussing Hello! Project using Discord. Discord is a chatroom client that can be accessed via their desktop program and mobile app, and even by internet browser. You can register for an account here and download/access the browser version here. It's currently pretty small, but we have a good group of active members so far and it's a nice chill place to talk about what's going on in H!P. Hope to see some of you there!
(Staff, if posting this wasn't ok then sorry! I couldn't find any rules against it. I'm not profiting off the chatroom, and I'm not intending to compete with H!O in any way.)
EDIT: Probably should've put the link to the actual room. Here you go.
