I was talking to a friend and I was muted due to being rude in #osu and my friend was wondering how long I was muted for. Of course I wasn't able to tell him. It would be better if when you send a chat message to someone who is muted, it says that they are muted for (x) minutes. I understand that they could simply go onto the person's user page to check but it would be less hassle if it told you in-game.
