like i had an idea where you add a certain number of review copies and users get the addon for free, and their review will actually be due at a certain time in order to keep using the addon. maybe there can be an option in the ACP where you can set the number of review copies.
maybe there can...
oh yea sorry I was using the serial key product type, I think digital works better for my scenario. and this is not an issue anymore, and it looks like I can still generate license key with the digital option?
Is there an example of validating license key? I have a license key field in my addons option that has a custom callback ideally I want to validate the license from there.
