UPDATE: New sites have been added! I’ve removed a ton of directories that were dead or dying and replaced them with new higher PR directories. There are now a total of 593 working directories. Most articles (depending on length/category/# of links) should be able to successfully submit to 400-500 of these directories every time! (Ex: I just completed submitting a 400 word Internet Marketing related test article with 1 link successfully to 529 sites)
More info on getting setup at the new Jetsubmitter Support Forum
Enjoy!
