Subject: A quick favor: one minute Hi everyone, We've been listed on Vendvera, a free directory of vendors that California homeschool charter schools approve. Families use it to find providers their charter has already approved. Our page is live, but it doesn't show any families yet, and that number is the first thing most families look at. If you come to us, would you confirm it? And if you have a minute more, tell other families why your kids love coming here. https://homeschool-vendor.vercel.app/vendors/3109 You'll sign in with your email so it only counts real families. The review is optional. It's offered right after you confirm. There's nothing to buy and nothing else to do. Thank you. It genuinely helps other homeschool families find us.
