Fischer Random Chess

Is there an option to challenge someone to play Fischer Random Chess, on RHP ?

In the red bar above, "new game". On the left side of the screen that comes up, "set up your own board".

But the castling rules doesn't work, so it isn't really Fisher Random you play.

Russ, when do we get Fisher castling? If you make Fisher castling work in normal chess too, then we wouldn't notice anything. Just change the castling subroutine in your rules package. And then it's done.
