The forum is the preferred way. I’m very glad you’re asking here!
That way others can also contribute their experience, and the result will be available to others in the future.
The email is available too, for those that need it, but that’s usually something to do with billing or sorting out their account.
Sometimes I get emailed questions that would be better here, but I answer them there nonetheless, no point in making them post it here before I answer.
So emailing is possible, and is preferred for things particular to the account, but for technical questions the forum is better. And I will answer either in either place.
