Please check this link: http://products.softsolutionslimited.com/news_publisher/index.htm This webpage has a 'Download News Publisher' button at the bottom. I need to build a software similar to this application. Some features of the software are: 1. A limited free feature that will submit the PR to only one site 2. Once paid, an activation key is sent to the user and once activated, it sends the article to multiple sites 3. Managing CAPTCHA of the respective sites 4. The software is readily integrated with over 100 PR websites. Need to build a similar system The software should be .exe based and should work out of the box without requiring any customization from my end.
