Hi Damian,
Thanks for getting in touch 🙂
1. Question: With personal license is enought to have the same addon in both?
If you wish to maintain a dev/staging site you are welcome to do so and a personal license should suffice (though, you generally don’t need to add the license to the test site).
2. Question: Community events is related to Pro version?
No, it’s not – but it does work well with Events Calendar PRO. However, all Community Events really requires is for our free, core plugin (The Events Calendar) to be installed and activated.
I hope that answers your questions but let me know if I can clarify anything else!
