I created a Toolset Theme at https://toolset.com/account/themes/
I want to distribute it to many installs
But it says "This theme can power only one site."
So I clicked "Upgrade My Account to Author", even I have a lifetime all-in subscription.
On the page thou it says You already have a subscription with all features > Go to downloads page
So - effectively I cannot distribute to many sites, not even if I would want to pay additional (which I don't really want to).
Currently, we have suspended the Toolset Theme Authors, pending some testing and review. We will publish an article about it as soon as we activate it again.
You can always ask more information about the program on this form https://toolset.com/home/toolset-for-theme-authors/contact/
I hope this answers your question. All the best for your theme project.
