Any recommendations for "website as a service" a la Squarespace, Wix etc. for a UK primary school?
They're currently on a WordPress site, custom hosted and I think they'd be better off on a "platform".
Needs:
- Admin users would all be very much non-technical
- No sales
- Mobile-friendly
- Decent performance
- Secure/private
Typical stuff I spose.
TiA. Boosts would be appreciated!
