Hey @billhudson,
Your concern over appropriate licensing is greatly appreciated! But no worries here – a license is not required for any plugin functionality, at all, so you can just activate a copy of your plugin on your test site and leave it unlicensed.
All our licenses do is sign up the sites they’re activated on for automatic update notices, and for customer support. So if it’s just a temporary test site, you can just leave it unlicensed, do your testing, and proceed from there.
Does this address your question? If not, I’m really sorry – let me know what I didn’t address and I’ll try to be more accurate in my next reply! 🙂
Cheers,
George
