To the best of my knowledge, Connie, it's organic. I link back to the site from around the Web and carry the link on my email, as I believe others do. Word of mouth and the fact that Health Central is very large, as a network, gets the search engines going. Traffic builds. People like you are important. Spread the good word!   I am not in a position to say that there is no advertising, but I think most of it is in the form I mentioned. I've mentioned the site on radio interviews and in other work I do. Again, I would think others do the same. We all want to see people find the help they need, so we spread the word.   I've mentioned it in my newspaper column a number of times and carry the logo on my own site. Others do the same. Good things generally grow. It takes time, but when people catch on they keep coming back.   People like you are really what makes it work.   Carol
