Problem :
How do I know with what software the site was built with ?
For example , did they use Joomla , Drupal , SharePoint ...
Solution :
- there is an addon for Firefox and cheome that can show you the software used to design the web site , what is the web server used and other information .
- it is called "Wappalyser"
- You can check this with an online tool on http://webmastercoffee.com
- It gives you allot of information on the site and its design tools
