Useful Drupal Modules
We use Drupal as CMS for our website projects at work. The Drupal world lives from its modularity. By now nearly nothing exists that has a web frontend you cannot realise with Drupal. You can create everything with specialised modules from a simple blog over e-commerce up to erp solutions. As of writing this there are 32945 modules on drupal.org. Some of them are probably outdated or only available for version 6 and prior. It is nevertheless difficult to keep track of all the important modules.
