What's the difference? AdobeRGB and sRGB

If you want to post or send better looking photos using the Web, convert your AdobeRGB photos to sRGB. Many point-and-shoot cameras are set for sRGB, so no problem for you. But, like me, I shoot all my photos using AdobeRGB color space which is great for ink jet printing, but it produces less pronounced photos on the web...like on this site.

How do I convert in Photoshop? Do the following:

Edit>Convert to Profile
Set the Destination space to sRGB
Set the Intent to Perceptual
Click OK to convert

I'll post an sRGB and hope it works. Or send yourself an e-mail with both versions of the same photo. The difference is VERY clear.
