Hey guys...
I was just contacted by the head of the beta program. He understands that some folks are leary about giving them their DISH account number. They need it to verify that they are an existing Dish customer in good standing. Remember SLING is owned by DISH / ECHOSTAR they are not trying to steal your account information.
He is also very sorry that this has been a slow process as theye have to go through multiple steps with different departments to get everyone approved.
He also mentioned that they have opened up more slots so if you didn't apply yet there is still time left to get in.
I have a feeling what your going to be testing could be big news at next years CES.
