Signs are simple notes you can place on any map square completely free of charge. They are coloured in your company colours.
Placing a sign
To place a sign, choose the landscaping toolbar and the furthest right icon on it. Then click a square on the map on which you want to place the sign and enter the text you wish to see there. Remember that a sign can hold a very limited amount of characters, so you might want to place a few next to each other.
Editing a sign
To edit a sign, click on it. An input box appears. Simply enter a new text and click "OK".
Removing a sign
To remove a sign, just edit it and remove all text in it.
Click and hold on a map icon. You'll see a "Sign list" there, where all signs sorted alphabetically are listed there.
