Hi there, I’m one of the CM’s both here and in Discord! For the ‘you can’t send messages’ issue, please try fully closing the Discord App and re-opening it. If you’re using the browser version, try clearing your cache.
Given you have only just joined, and I have only just clocked on today, it’s highly unlikely anyone on our team has taken action against your account. If the above doesn’t help, you may need to check your emails and see if Discord needs you to verify your account in order to post.
