Where can one find screenshots or demos of Drupal modules?

I often find myself searching fo开发者_JAVA技巧r a Drupal module for a particular purpose on drupal.org/project/modules. However, the descriptions there give very little information about the end user experience. One module I recently looked up is Related Links. The description sounds as though it does what I want, but I have to wireframe a site using it, and I have no idea what the UI is like.

Is there a good central source for screenshots or demos of Drupal modules?

There is NOT a central repository of Drupal module demos. Sometimes the module author will setup a demo site. Look on the project's page (on Drupal.org) in the right sidebar under "Resources". Sometimes there is a link "Try out a demonstration" or "Read documentation". If it isn't there, then you will need to try installing the module yourself or search the Internet for documentation or examples.
