In my workplace (a US high school) I am the sole TeX user, and have been for a while. So I'm curious: are there any other secondary school teachers (not necessarily in the US) on tex.SX? If so, what discipline?

EDIT: `learning` isn't a good tag for this post, but I couldn't find a better one and don't have sufficient reputation to make a new one. If there's a more appropriate existing tag, let me know.
