Hi there,
users who purchased the license before the recent price changes would still continue to receive the old licensing policy that provides unlimited sites.
As Leo said, with the new license, we are happy to review anyones site limit in the future, but we have yet to see any license exceed 500 sites that were within the terms of the license.
Consider if you were to create a new site every week it would take 10 years before the license cap is reached… thats a hell of a lot of sites for any user, even Agencies rarely generate that number of sites.
