Share your themes
The theme you save is yours: you can do whatever you want with it. Fill in the form with the name and the author, your name or your nickname, so it is identified when you share it.
The theme file
When you export, your theme is saved as a .rth file. That file is what you share.
Sharing and selling
You can share your themes with the community on the forum or on your social media, and sell them on platforms like Gumroad or your own online store.
Using it another day
Whoever receives the file imports it from the theme editor, and can apply it to their workspace or keep editing it.
