Help Topic : 1. What's NA Chess Hub (aka NACH)?
NACH stands for Not A Chess Hub. It is a web site that provides a collection of services to chess players and organizers for event publishing, promotion, marketing and of course, registration and payment processing.
Some people creatively think NACH stands for North American Chess Hub but that's not a true statement as we support organizers from countries located out of North America. As long as you have a FIDE ID, you can create organizer account on NACH and use it to organize various chess events. See detail at Create Account
