WP Multisite licensing requirements
When purchasing some 3rd party themes or plugins, etc, they frequently post 3 prices, ie one for a single site user, one to install on multi sites, and a developers version (for client website). If I have one install of WP multisite on a domain, but with several blogs in different subfolders of the same domain, would I need to pay only the single user license or would I need to purchase the multi site license?
