I thought you were supposed to put a link to your sitemap in your robots.txt (isn't that what you said, stymiee?)

My robots.txt now looks like the following:

Sitemap: http://www.daniweb.com/sitemap.xml
User-agent: *

Google Webmaster Tools robots.txt says "Syntax not understood" for the sitemap line.

You can. Google announced it in their blog. Looks like they haven't updated their webmaster tools to reflect that. I wonder where can inform them of it?

Oh!!! This information is really helpful. Does Yahoo have a nofollow facility?

They say they do but many people also claim they haven't implemented it yet.
