I made that unforgivable sin of cartographers - I merged the layers and saved as a JPEG...thus, I can't lower the opacity (at least via any method I know). We play with a projector shining upward on our playing surface and often the grid isn't very visible, so I have to over-do it a bit. Next time I'll save with the layers and/or remove the grid altogether.

I used Paintshop Pro 8.0. Don't have Photoshop. Some day, some day...

Thanks,
D
