What if I bought the plugin before the yearly subscription model went into effect?
If you purchased WP Courseware when we were offering lifetime support and lifetime updates for free, then you will be "grandfathered in" and keep that same deal. You can keep your current license, whether it be a single site, 2 site, or developer license, and receive updates and support for the life of the product. The only caveat to this, is that you can not upgrade your license. For instance if you have a single site license, and you want to upgrade to a 10 site license, it won't be possible. You can purchase a 10 site license, however, the license will expire in 1 year in which you will have to renew yearly.
