I am looking over Sean O' neils page, as well as Petrocket "Simple Flexible Atmosphere shader". I tried to copy/paste them into my project and nothing seems to work...at all. I'm sure I'm supposed to use the "set effect technique" command but I'm not sure which technique I should set.

I know that the shader effect is to be applied onto a sphere that's a little larger than the planet. I also know that the planet must be in a fixed position as well as the light source location must be fixed.

I read that an small image is used as a lookup table for the shader math for quicker calculations. I wonder if I can change the color hue of the lookup table in-game on the fly. Or at least alter the shader in-game to use a different lookup image.

There must be a "atmosphere shader" for dummies somewhere. One step at a time for me I suppose.

Can you post the example?

Did you make sure the sphere has a negative size so it's visible from the inside?

so the shader sphere has to be a negative size so it's effect can be seen from "space" and on the "surface" of the planet?

Well if you're using make object sphere to create a sphere around your world, you won't be able to see it on the inside because the sphere's faces are only visible from the outside. You can fix this by doing either one of these:
