Drupal 8

Scald is a popular and flexible way to handle media in Drupal.

Provides streams of status updates like Twitter or Facebook's "wall" feature: each user/node/group/taxonomy term/whatever can have a "stream" or microblog where users can express their thoughts to the community. @mentions and #hashtags are supported, as well as comments on status updates, viewing conversations between users, the ability to "like"/"reply" to/RT a message, automatic updates without page refreshing, and integration with over 25 modules.

Facebook-style Statuses is moving to the Statuses namespace for Drupal 7+.

Allows users in permitted roles to add custom help messages to any specific path or path pattern, for display to selected roles, along with help messages provided by other modules.

This module provides an API to consolidate images into a single sprite image.

When an image hits the sprite registry, it will be entered into a static array. At the end of a page load, all so entered images will be consolidated into a single image made up of them all, and a CSS file will be generated to properly display the image. The registry array will be saved to the cache with its md5 hash, so that future sprite images of the same composition may be retrieved without rebuilding that image.

Two related projects, CSS Sprites and CSS Sprite Generator, work with themes, and purport to work on the theme level, replacing theme css files with the sprite files. This is meant to work in conjuction with that, but using page generated images, such as image fields. In the future, as this module simply provides an API, they may work together, ultimately creating one single image and CSS file for all images and CSS background images on a page. For now, you could, in theory, use the two modules together to create no more than two image files for a single page.

How to use the sprite module:
* theme("sprite", $filepath, $alt = "", $title = NULL, $attributes = array(), $registry = "general", $override_width = NULL, $override_height = NULL, $offset_width = NULL, $offset_height = NULL)

Provides a complete subscription system by email. Create different mailing lists / campaigns and place subscription form blocks for them. Anonymous and authenticated users can both subscribe. Subscriptions are fieldable content entities (only D8), so it can be easily used in views or in any other module.

A Notifications plugin that allows users to subscribe to information updates based on a node's taxonomy. Primarily designed to integrate with nodeprofile to allow people to tag themselves, and receive updates based on the terms they have assigned to their nodes.

Usage examples

This module has been developed for School of Everything to keep users up to date on their interests. We use this module in conjunction with the taxman to allow users to tell us what subjects they are interested in.

This module also interfaces with Taxonomy NCO to provide notifications of similar subjects. Taxonomy NCO performs analysis on large freetagging vocabularies to infer semantic similarities, or 'other things that people might be interested in'.
