I’ve done RPs on Instant Messenger (MSN, AOL, Skype, etc.) for nearly twenty years. They are a medium between Chatroom and Message Board that aren’t all that different. For me, the RP on Discord messenger can be no different than a well-written casual section post on RPG, though that [u][b]entirely relies on you having the right partners[/b][/u]. There is no difference in genre or style of RP between messenger and forum. Some messenger groups will prefer a touch-and-go style, others will look for something more well thought out. I've had all kinds of experiences through the medium. I prefer it far better than chatroom RPs that rely more on posting speed than cohesive content.
