Add "SEO" category to "Modules categories" list for SEO-related modules

Absolutely agree with this. Was just looking in the list for precicely this and thinking the same.

SEO definitely needs to be added.

Seems reasonable to add it.

The parent terms in the vocal are all plural (Modules, Themes, Theme engines, Distributions, Drupal.org projects) so it probably makes sense to make them singular.

admins: it's taxonomy/3

If no one else opposes, I'll fix both in the next few days or so.

+1. Do it! :)

I have added it: http://drupal.org/taxonomy/term/36748.

I have also changed those taxonomy terms (the ones referred in #2) from plural to singular.

I'm guessing you broke all links with that?

http://drupal.org/node/1627228

The plural / singular change was reverted.

I've changed top level terms back to plural because of #1627228: Broken link to the Modules Page.

The links to those pages are hard-coded in drupalorg_crossite.module.

  $nav_footer['column_4']['#value'] = theme('links', array(
    array('href' => 'http://drupal.org/download', 'title' => t('Download & Extend')),
    array('href' => 'http://drupal.org/project/drupal', 'title' => t('Drupal Core'), 'attributes' => array('title' => t('Download the latest version of the Drupal software'))),
    array('href' => 'http://drupal.org/project/modules', 'title' => t('Modules'), 'attributes' => array('title' => t('Download add-on features and functionality'))),
    array('href' => 'http://drupal.org/project/themes', 'title' => t('Themes'), 'attributes' => array('title' => t('Download pre-designed styles for Drupal'))),
    array('href' => 'http://drupal.org/project/distributions', 'title' => t('Distributions'), 'attributes' => array('title' => t('Download a pre-packaged Drupal site'))),
  ), array());

I apologize for the problem I created.

Do *not* touch any top-level taxonomy term. Never. Ever.

Drupal.org is running Drupal 6, which stupidly mixes human display and machine name for taxonomy terms. Until we migrate to Drupal 7 and have the ability to add more fields to the taxonomy term entity, please don't touch that.

Right, for the record all of the following were (re)opened in the wake of this change:
#1247730: Re-enable http://drupal.org/project/modules/index
#1627228: Broken link to the Modules Page
#1627292: Link from issue to project page is missing
Granted, lots of this is just fragile code in drupalorg_crosssite, but still...
