I use Craigslist to advertise however I think the information shared about (eZinearticles, GoArticles) is a good idea. Also what I do is I use my vacation responce in yahoo. For example when I get spam or emails from friends or people responding to my CL ads, a vacation responce is shot back with information on it. I have a few websites but the main one is
THE WAH List Work at home.... |. It takes time however if the site has some good content word of mouth will also carry it far. I update and work on my site almost everyday. It's important to not only let people know about it but again give them a reason to want to come back.
If you find something that is really working with you I hope you can share it with us.
Good luck and I hope I helped.
