In your opinion, how to quickly join the database?

Answer 1

Hello!
As far as I know, you can use the key only 1 time (I checked it myself). But you can leave out the key and reset the subject (if required). Some themes work without a key without resetting, and some only work with resetting.
Or, for each site, buy your own key ...
Well, or purchase a key for developers of sites of the extended type

Answer 2
