someone help me with communicating with the other players
At the bottom of the table you are playing on click into the little oblong box and type your message then push the enter on you computer, laptop and the message will come up. Hope this will help you.
If you want to send a private message to a player, then you can visit their profile page (there’s a search players form on your dashboard: http://www.replaypoker.com/dashboard) and click the Send Message button. On the new replaypoker website it’s even easier, there’s a messaging section available from the player dropdown menu in the header of the website.
