undo moves with friends?

"Daily" used to have a takeback feature, unrated of course. Let me see if I can find it without accidentally starting a game...
Sorry, I clicked all over the place and couldn't find it. Support would know if it's still a feature, but it might take a while before they get back to you.

Sigh...As usual, just because I can't find something doesn't mean it doesn't exist! This is from the article on Daily Chess. Guess you have to hit the More options button to find it.
- Allow takebacks? - this option is only available for non-rated games. Takeback games allow for players to take back or ‘undo’ moves that have been played on the board. This setting is often used for teaching purposes.

Where is this option located? It doesn't appear to be in the "new game" or "invite a friend" sections?
