Follow-Up:
There are many reasons why you should let a submissions company provide your search engine submission services. The first being your time. The second being the fact that the software has tremendous flaws ( invalid engines in the submission list and the major search engines disallow search engine rankings). Use a submission service that is on the ball-(some of them provide a good service for just 10-20 dollars a month). I have used a different one for each of my various url's and I have found SubmitCo.com to be the best as of yet. All of their engines are valid, they have a very informational search engine optimization how to page, and they have their own search engine submission technology that submits your site. Other then that I would say quit your day job and do the submission yourself.
