Well, I can see three solutions.

Solution one: Everyone looks up the full name of the team, which should list a school or two. Google that, and make some calls. It's a pain, but surely there aren't multiples of the same school in the same town. And hopefully whoever answers the phone at the school's front office knows who does robotics at that school. (If they don't, shame on them!)

Solution two: Someone with time and resources puts together a massive FIRST-independent contact database. Main teacher, emails, addresses, phone numbers, submit as much or as little as you're comfortable with.

Solution three: Beg for FIRST to re-enable viewing directory information in TIMS on an opt-in sort of basis. Like you have to go to a specific page and deliberately enable it. (Someone more familiar with TIMS might be able to picture this better than I can.)
