Please note that the Market Client is out on it's first public beta test, the idea being that we can get all of your feedback and fix any problems to produce a perfectly working client.

This is the reason we are releasing stable QT wallets, so you can stake and send/receive with them while we develop and test the full client.

The beta Market Client will go through many changes before we release a final stable version, so as always with beta software, use with caution and expect some turbulence, especially in the early days.
