I want to share some my useful modules for Drupal.
Including:
1)Lite printable version module (port of printversion-5 from http://www.drupal.ru/node/10983)
2)Module which creates pages as a combination of views, nodes and other content.
3)Module which limits maximum attachments count for core upload module
4)Module which adds extra form elements, like dynamic AHAH table.
5)Module which adds extra core profile field types.
