I am a fan of DrupalModules.com, I really am. But I am frustrated that not all modules from Drupal.org are on DrupalModules.com
For example, I was recently searching for the "Desktop Notify" module which is available on Drupal.org: http://drupal.org/project/desktop_notify
This module was added in March 29, 2009 - yet is is NOT available on DrupalModules.com
When is this issue going to be fixed?

That module has no published releases.

As noted at the top of the "New Modules" page:
"Modules must have at least one release published on their project page before they are shown here. This helps to keep unfinished modules from cluttering the results."
It looks like Desktop Notify has no published releases:
http://drupal.org/project/desktop_notify
Compare with this module, which has a published 6.x release listed:
http://drupal.org/project/menu_css_names
The author of Desktop Notify needs to take the initiative to mark one of their releases as working before it will show up here.
