hello i am new to drupal . i want to create a website which will offer content download similar to this website http://drupalmodules.com it will helpful if someone can tell me which module they use or similar to it thanks
Usually, I recommend just view source code. It containes list of modules. drupalmodules.com uses google_analytics module
As far as I can see they use Views ( and most probably CCK too ) They have optimized their js n css so I can't get more info the usual way.
Creator of that site himself told what he used. Search the forums there. It's usually CCK + Views, code that fetches info from drupal.org is custom i'm sure, and review functionality is custom code as he said.
