Discord is a slick tool for real-time chatting amongst a number of people. There are some strategy chats that happen using this tool, but the primary use within the RecPoker community has been real-time railing of each other during live events (which we hope will happen soon).
There is a very slick mobile app that allows you to stay connected even when on the go! Check it out and join the conversation.
Once you have joined, poke around and engage in the conversation. If you are playing in a home game, JOIN the voice channel to chat (and even do video) with others in the game.
