I want black letters on a white background

Of course, there is a temporary solution. I copy the text from the game into the notepad (Windows application). There I have it in black and white and I read there. Then I write in notepad and copy the text into the game.

Tiring, but it works.

Good example how it should looks like.

Conflict of Nations game.

I like the arrangement of the CoW more, but it's more comfortable to read news and posts in CoN.

As picture shows it was made well in the old days. Black letters rule.
