It is legit. If you read the fine print, you'll see that there is a "cost": The software adds a link in your author's resource box that says "submitted with Article Distributor", and Article Distributor is linked back to the software page. It also only submits to sites using the article dashboard script. It's free so I make no moeny from it if you use it or not, therefore I'm not going t o spend a lot of time debating it's merits.
http://www.after5webdesign.com/software.html I never place a direct link to the software because the source code is specific to MSXML 4. If your Microsoft XML parser is out of date, you'll have to upgrade it or you get an error. I'm sick of troubleshooting for people who tell me it doesn't work only to find out they never bothered updating their XML as instructed. To stem these kinds of reports, the page checks to make sure you have MSXML 4.0 by attempting to create an MSXML4 data island. If it fails, it displays the link to Microsoft so you can go update your MSXML. If it succeeds it outputs the download link. Obviously this means you must have a javascript enabled browser also. During installation, the software will attempt to install some MSXML dll files in your Window's System directory. Some anti-virus programs don't like software that tries to copy anything in that directory and will write protect it for you. This will generate a "No Permission" error (1935). If this occurs you can get around it by temporarily disabling your AV. If this makes you uncomfortable, you are welcome to go pay $100+ for one of the "professional" products like Article Marketer.
