ahh I would feel better if I can submit to over 2400 directories in under an hour. I know that there is a program that can do it.
Strongly suggest that is the 100% wrong thing to do, apply to 2400 directories with varying title and unique content description over 20 days and see the difference and while you are doing that select quality directories before you start the process
AllSubmitter - is the best directory submitter software. All other suits just tiny of it or plain crap. http://www.webloganalyzer.biz/eng/allsubmitter.html
The links that dont get rejected outright will eventually get dumped and those that dont get dumped will get devalued. Why waste your time and money? Besides which many of us would like to see a blacklist which means there is a good chance you could end up getting crap from a whole lot of directory owners as well as Google . Rather do it right first time out.
Roboform is best program for directory submission, although not fully automatic but i am really satisfied with it and save me lot of time. actually it is a form filler not a submitter, but still works will while submitting to directories.
Autosubmission is a very poor method and is likely to give you and your website a very poor reputation as a spammer... semi-automated is the way to go...
