Thanks to Pedro Cambra who code the 7.x version of this module.
This is the initial release of More comments for Drupal 7.
Provides the same functionality as the 6.x-1.0-beta3 release.
A new UI allows to configure per content type, if the morecomments button is enabled or not.
The button text is now configurable.
Note: Morecomments are disabled by default. Go to admin/structure/types -> edit your content type, and in the comments tab enable morecomments for your content type.
