You may also find that a higher number of dojos than you would expect don't have internet service.
Internet service? What's that?
Our dojo has a website, but it's for informational purposes. We're simply not large enough to need shopping carts or any other e-commerce paraphernalia. We're also not large enough to need specialized apps to track attendance, dues payments, testing, accounting/bookkeeping, etc. General purpose apps such as Excel and Quickbooks do that well enough for a dojo our size.
