Which Drupal Modules Do You Use?

Someone asked which 3rd Party Drupal Modules we use on our sites.

Not all of these are in use on every site but here is the list & what they do.

Adsense:
Incorporates Google adsense as a block or within nodes.

CommentMail:
Sends an email to selected users when a comment is added. The email contains links to easily moderate comments to posts.

DiggThis:
Adds a "digg" button to enabled node types for easy submission of pages to Digg.com by users.
Note: This only works in "full view" per the comments in the module code. It doesn't work on node teasers which are enabled by default in Drupal.

Event:
adds an events calendar for enabled node types.

Flexinode:
Allows for the creation of custom content types.
Note: This module does not play well with CCK which is similar in functionality.

Gsitemap:
automatically submits a sitemap to google when content is changed, added, or on cron run.

Nodewords:
Adds metatag control to nodes & pages including taxonomy pages.

Pathauto:
Automatically creates url aliases according to rules you define. Beware, it is very easy to accidently give a new path to your existing pages which have traffic or pagerank... resulting in a 404 error. Ask me how I know this. Not the module's fault, it works as advertised.

quicktags:
javascript widget to add simple & common html tags to content text areas. There are a few similar modules which offer extended funtionality (tinymce, htmlarea, & the aptly named FCKeditor... which I have never been able to get working). Quicktags is sufficient for simpler blog-type sites.

RobotsTXT:
adds an individual robots.txt for a single or multisite environment.

Sitemenu:
adds a "site map" link to the navigation menu or (optionally) a block with expanded categories to the sidebar. When enabled as a block it creates TWO titles... One for the menu name & one for the taxonomy (root category) name. One solution is to use css display:none to make this go away if you think it looks funny.

Technorati:
Enables Technorati tags for selected content types, and pings Technorati when new content is created.

Theme Editor:
I think I used this once. I tend to edit html & css for themes in Notepad.

Image & Image assist:
Allow easier management of images in posts.
