See, back already.
When you post images to the web or send them to a 1 hour lab for printing, make sure that they are in the srgb color space. If you are shooting in raw just make sure that the space in the bottom of the camera raw dialogue box is set to srgb. If you have a file in the rgb 98 color space just go to the edit drop down menu - convert to profile - destination space - srgb. Just do a comparison and you will see the difference.
I am not saying by the way to never use the rgb 98 space as that is what i use the most. It has a greater range than the srgb space. I use it for photos that will be seen on my monitor or photos that i will print locally (ink jet printer in office).
