@Marcelo Melgaço - The Guests fetaure is not available in the Starter Plan. Instead, you would use the Visitors feature to invite non-team members to edit your boards. There is no limit to the number of people that can edit your board as long as they have the link.

Here's a post with an explanation of of Guests vs. Visitors:

Thank you so much, Robert!

What about Guests vs Members?

You're welcome!

Members can

- Create boards

- Share with new people & change board sharing settings

- Perform actions or change the settings of the team dashboard. On their dashboard, they will only see and access boards shared with them

- View team members and access team boards

- be added to Projects

So kind of you, Robert! Thanks!!!
