Double / Redouble is described at Pagat as a popular variation of the game, and I've had several requests to add it. It works like this: the opponents of the team that declared trump have a chance to say "double" after trump is chosen. Then if the declarers do not make their bid, they will lose 2 game points instead of 1. If they do make their bid, they will win 2!
The declarers can respond with "redouble". If they do not make their bid, they will lose 4 game points. If they do make their bid, they win 4!
It only takes one player on a team to declare "double" or "redouble" - either player can do it.
The Double / Redouble Option is turned on by default. If you start a table using the default options, then Double / Redouble applies. If you do not want to play with this option, you will need to set the radio button for "Allow Double-Redouble" to "No" in your Options settings.

Tables which use this new option are designated with "drt" (it stands for "Double Redouble Twenty-Nine") in the list of tables. Tables with the Seventh Card option are shown designated with "sct".) In the screenshot of the list of tables below, the Twenty-Nine table has both of these options applied, and a single Guest is sitting at it:
