Reselling of this software or its derivatives is not allowed.
You may use this software for one website. Subdomains will act as a separate website and will require a separate license unless they are used as one admin multistore.
A multistore installation is okay with one license when all multistores domains are owned by one person or one company.
An ecommerce enabler site using multistore will need a separate license for each store.
