Installation

Scott from Level Up Tuts put together a great tutorial on how to install Disqus on Drupal 7. He walks you through these steps:

1. Download and install the Disqus module into your respective sites directory (sites/all/modules).

Flag is a flexible flagging system that is completely customizable by the administrator. Using this module, the site administrator can provide any number of flags for nodes, comments, users, and any other type of entity. Some possibilities include bookmarks, marking important, friends, or flag as offensive. With extensive views integration, you can create custom lists of popular content or keep tabs on important content.

Flags may be per-user, meaning that each user can mark an item individually, or global, meaning that the item is either marked or it is not marked, and any user who changes that changes it for everyone.

In this way, additional flags (similar to published and sticky) can be put on nodes, or other items, and dealt with by the system however the administration likes.

The idea behind the module is to simply assist someone with keeping an I Ching journal, not to automatically calculate the hexagrams themselves.

This module is a simple implementation of the XRDS-Simple spec, which used to live at: http://xrds-simple.net/core/1.0/.
