I was just curious. I'm a part of our district's (Des Moines Public Schools in Iowa) tech "innovator" group. I like the Invest in Tackk thingy. I will be presenting at our district's tech conf this sumemr and, of course, Tackk in near the top of my list of tools to present. I've made over 125 Tackks with 40,000 views. Feel free to share with your world language teachers.
