Hi Bernhard,
Thanks for reaching out with your BoldGrid Themes questions! My apologies, I’m not familiar with Mocha and we do not currently have an official partnership with that platform.
That said, they could have a premium license through one of our Premium Hosting Partners like InMotion Hosting or DreamHost. These platforms allow developers to purchase premium licenses and use them on their clients websites.
It’s possible Mocha uses one of these companies as a parent host. As long as you’re using BoldGrid products you’ll have access to this free forum here. We would just need official BoldGrid account credentials to login to our Premium Services to access the free premium plugins included in our plans and for premium support.
I hope this helps. Please let us know if you have any other questions for us!
