Congratulations. You can do pretty much anything related to education as long as you don't promote education to the congregation. I was an elder going to graduate school. I never told anyone and if anyone asked I simply said that my employer required me to go to school - I never entered into a discussion and certainly not a debate.
I actually am not going to be shy about it. I'm going to mention in casual conversation things like, "The other day in _____ class we were discussing _________ and an interesting point was brought out."
I can't wait for my privileges to be taken away.
