well, not to fuel the fire, but we have some overlap with both @Calliemomofgirls and @dadof4kids and we have received no such emails.
But - I do not think this means anything in regards to being targeted or checking “interest”. (I say that more for MY peace of mind than anything else…LOL).
I think post M10 would be the time we would visit these opportunities, also. I would think (hope?) that schools would provide this option as part of the “revisit” process.
