how to change permissions

Yellows and oranges are our own files, so we're in familiar territory here. But we can see that Maelstrom and Myst are publicly writeable! We can't have that.

We'll tighten the permissions on Maelstrom.

Right-click on Maelstrom, and choose the Edit > Permissions > Deny Write > to Everybody submenu.

After a small delay, you can see the permission changes.
