I got an email saying that my opponent has offered a draw. yet when I go to the game, there is nothing there to indicate a draw offer, and it is still my move. How do I accept a draw?

An aceptance bar should appear for the draw,if not tell them the issue and offer the the draw and it may work for them

if your opponent offered a draw and you have since moved by then (i.e. you didn't notice the draw offer at first), the offer is declined and disappears.
