What is the ownership of answers?
I started teaching languages when I was an infant and several of my students have reached a level very close to native speakers. In order to still be able to teach them something, I have a huge collection of my own observations about subtle differences that tend to escape our eye. I have never wished to publish any of this, but I don't want to exclude the possibility of me or my family doing so some day. Today one such question appeared on stack exchange.
Will I encounter copyright issues if I ever publish my own answer?
