Hey, no worries, it's easy to mix things up 😊. Great that you can now use the Free Edition haha! 

@szymon_dybczak  has provided the link in another post where to sign up. You could also try googling "Databricks Free Edition" in future.

Just be mindful, if you use the same e-mail that you created a trial with, there could be some clash there. If you experience that, I'd suggest just using a new e-mail 😊. 

If you want to know what sort of limitations the Free Edition has, they're all listed here: https://docs.databricks.com/aws/en/getting-started/free-edition-limitations , the Free Edition is awesome btw 👍.

Once you're up and running with the Free Edition, I'd love to hear about the projects your using it for. Always looking for inspiration 💪.

All the best,
BS
