Far as I know Curt, you have to manually change the color/font size/style each time you make a post. I use the one you see here simply because the default one I have a tough time seeing. The eyes aren't what they used to be, and this "dresses" things up a bit than the too faint black font.
Thank you, that's too bad...I have the same problem with the itty-bitty default font!
You can hold the "CTRL" key and tap the "+" key until you get it large enough, "-" key will reduce it. You can also change the font and size in your browser tools.
