All your boards are located in one Team: Solvay - Digital Visual Management.
This team can be open to external partners for a specific project but new licence needs to be asked on Freshdesk.

To create a board... click on the big blue button on your Dashboard.

If you choose a certain project within the working space - the board will also automatically belong to that very project and will be shared with the project's participants.

It can be seen beside the project's name: 

After you have created the board, you can change its title, add a description or set a cover picture in the board settings menu or add it to a project or Favorites (star it).

Here you can also share, duplicate or delete the board.
And you will also see when it was created or edited.
