Customizations used on Drupal.org itself. It is not meant to be useful to other sites, except as an educational example of the kinds of modifications you can make via a site-specific module.
Provides a search tab which pulls results from the Bing web service. The search query can be limited to a set of sites, and various advanced search query strings can be used (or appended to all search queries).
The 2.x branches of this module support the Bing API 2.x; the 1.x branches support the original Live Search API 1.x.
Vocabulary Index provides an easy way to create a taxonomy browser / directory index. You can choose for which vocabularies to create pages or blocks where the terms within that vocabulary are listed. With just a few clicks you're done. Listing is possible in different kind of views depending on your needs:
The tree view displays all terms in a nested tree. If visitors of your site have JavaScript enabled, parent terms will be collapsed by default, but they will expand when clicked on. Since tree view displays all terms on a single page, terms with multiple parents are displayed more than once: once beneath every parent.
The browsable view lets visitors browse a vocabulary much like they would browse through directories on their hard drive. Taxonomy pages of parent terms do not list the nodes within those terms, but the child terms it contains. Since blocks cannot span multiple pages, they can be displayed using a flat view. This is exactly the same as the browsable view apart from that it is not browsable. Browsable index pages are pageable.
The alphabetical view sorts terms by first letter. Optionally character transliteration may be enabled. Alphabetically viewed index pages are pageable.
Once installed (see README in the archive) you (or any user who can post) can add an embedded href link to any node using the syntax (where N is a number, and NNN is a node id):
Answers enables the implementation of a Question & Answer system in a Drupal site. Users can post questions and other users can answer them. To see it at work (based on the most recent 7.x-4.x-dev version), head over to its Demo site and have a look at the Questions there.
