I have created a new prediction market http://cryptofresh.com/ENDWAR. 

This asset is backed by USD, but the GUI is still trying to back it with BTS.  @svk would it be possible to change the borrow mechanism in the GUI again so that it backs this asset with USD?

This asset will be worth 1USD if the current war in Yemen ceases before January 1st 2017.  I decided to create ENDWAR after reading https://www.reddit.com/r/BitShares/comments/41wjnc/anyone_working_on_implementing_social_policy/  If someone would like to promote the end of this war they can borrow the asset and either give it away, or sell at a very steep discount to activists that are working to end this war.  It is a great way of raising money for a cause you believe in while only risking your money if the result you are looking for is accomplished.
What other ENDWAR assets would you be interested in?  ENDWAR.IRAQ  ENDWAR.SYRIA  Any other social goods that you think we could accomplish, that you would like to see a market for?

I have created the prediction market REPGENSIXTEEN.  every REPGENSIXTEEN will be settled for either 1bts if the Republicans win United States general election in 2016, or 0 bts if any other result happens. 

There is limited support in the GUI.  You can buy REPGENSIXTEEN like any other smartcoin.  Shorting is currently prevented by the GUI because there are no feeds.  If you would like to short you will have to do this in the CLI wallet.

Collateral must be 1 for 1.  If you want to borrow 1000 REPGENSIXTEEN you will need to put up 1000 bts.  This is a smartcoin and is collateralized by the blockchain.  This is not an IOU.
