I just installed your plugin and am logged in. I can’t find any place in my admin dashboard from where I can reply my sites visitors chat.
When the chat starts, you can see and reply your incoming messages in your online chatroom at www.wp-chat.com, into which you need to login with your email and pass that you used when you registered and activated your chat plugin. All incoming messages from your visitors will be reflected in section “Online chats” in your online dashboard. When you get a message you will hear sound notification and the active chat will appear in “Online users (active chats)”.
