Now that I think about it, I rarely see DIRT posting anymore. Perhaps DIRT is being utilized a little too much by some? But there's also the fact that many of the members here offer helpful suggestions that solve a lot of the problems.
When I needed some of my receivers activated, I just used the online chat @ dish.com, since it wasn't complicated. I utilize DIRT for things such as bug reports and new installations. MattG, MaryB, ZachS in particular have been very helpful in situations that would've otherwise been a nightmare if handled through the bottom of the chain. Since DIRT, I have not had to utilize the executive offices, except for once, but that was after contacting DIRT and the executive offices called back. I'm sure the other DIRT members are just as helpful.
There are three instances in particular that were a delightful experience. In chronological order, the first amazing experience was when MaryB chatted with me on the phone and got my 722k account set up. Next was a nice phone conversation with MattG and prompt help in my first Hopper upgrade. Last, but not least, was a PM conversation I had with MattG. I had a three-Hopper setup at the time, but due to a software bug, the Hoppers would randomly lose contact with each other. At first MattG didn't think that three Hoppers could see each other anyway, but after a brief explanation of the issue, and a diagram of my setup sent, he determined that it was indeed a software bug. He said he would report it to the software engineering team. Less than a week later there was a software update, and all issues cleared up. That would've been a total nightmare to explain to the typical CSR.
