what are the sites that submit to multiple directories for free and is there a script for this somewhere?
I would suggest don't use automate submission just like ahkip said most directory don't allow them. But if you really want to do it visit this http://www.submitexpress.com/submit.html
Good directories do not allow automatic submission and submitting to FFA sites is pretty much waste of time/money unless u r targetting very crowded niche and want every possible link. Look for quality links and from blogs
*sigh* Somehow I dont' think that they deserve the live link which angelfire has provided to there site. They will sell your email and will spam you like hell.
I am not sure how automated submissions work for directories, since for most directories, you need to select the most approporiate category that fits your site, and most directories have different names for the most inner directory that fits your site, automation is not a good idea, I've seen automated search engine submission, but not for directories. However, there are services that submit your website to directories MANUALLY, and you will have to pay them.
