# Helper that creates a chat-text box

module TaskHelper

  # form on the page when it expires.
  # The helper emits a +<span>+ with +id="_chat_"+;
  # its *presence on the page* causes a  
  # websocket to be created.  See +chatpage.js.erb+ for the chat code.
  # Only one chat per view is allowed.
