Since you're interested in learning DigitalCAT, I recommend you join the group here on CSR Nation. I believe they have one. And just read through all the threads there for more info! ;)
Also, please check out my blog -- stenonerd.blogspot.com. I'm a court reporting student too, and my blog is basically me talking about my progress in court reporting school and being a source of encouragement to fellow court reporting students. Thanks in advance for checking it out!
