Probably best off going to 2 + 2 in the marketplace forum. There are plenty of sites out there that do W$ and T$ transfers, but since you have quite a bit of money to trade I'd post on 2 + 2 and see what sort of exchange rate you can get.
But seriously, unless Rex plans on playing that $1050 event, I don't think anyone here has much use for those W$. You should get a decent return at the 2+2 marketplace though.
In addition to Tournament Dollars, we also offer special W$. W$ can be used to register into any qualifying special PokerStars event.
Special poker events include:
When you win a seat in one of the W$ special events, for example a seat in the PokerStars Caribbean Adventure event in the Bahamas, you will be required to play the event and will not be allowed to unregister. If you win multiple seats in the same event, the value of these seats will be automatically credited to your W$ account. If you win a seat to a satellite for a W$ special event, you have the option to unregister from the satellite and receive W$. W$ can be used to register in any W$ special event.
