Thank you for your detailed and insightful comment. I really appreciate the time you took to type out such a lengthy answer.
I'm definitely not attached to learning about e-mail; I was just using that as an example of one of the things that interests me. I can let that go pretty easily.
As far as not being able to train as much as I would expect--I currently deal with that exact situation now. The majority of my job consists of developing and delivering training to teachers on various technology items. Scheduling is always a problem, especially across teams, departments, or grade levels. It just makes it all the more fun when I actually make it happen. I learned about "food bribery" long ago, and typically try to make it fun by providing stuff like that at my trainings. $20 on coffee and donuts is a huge morale booster and starts my sessions off in a great way.
I do pride myself on my communication skills and enjoy teaching folks how to use the software and websites we use. I tend to absorb these things pretty easily, and can intuitively find my way through most of our stuff, with or without training beforehand.
One of the reasons I'm asking around now is that I don't plan on seriously looking for something until I finish my master's degree later this year. This gives me a little bit of time to perhaps learn some skills and chart a rough course of what I'd like to do. Learning something that quickly becomes outdated is a situation I'd like to avoid--so I appreciate you sharing the "buzzwords" heads-up with me. Thanks again.
