Drupal add-ons (modules) to consider for the Edubuntu website.

Note: This page lists all modules that sound useful, grouped by categories found on the drupal.org site, in alphabetical order. Also note, some of the module might not have been ported to work with the latest release yet (Drupal 6.x).

Drupal Core Modules (Issues)

Blog API - Posts submitted via Blog API can't be assigned their Taxonomy.
Form submit - rapidly clicking on the submit button of a form will result in duplication of nodes/users, see discussion and suggested solution at http://drupal.org/node/107358 alternatively, if an immediate solution is needed, try the 'form single' module http://drupal.org/project/formsingle
Upload - Don't enable this? Possibly use 'IMCE' or 'File framework' instead. Update: file handling in Drupal 5.x is still sub-optimal, a new file api is being worked on.
- See "Race condition in upload module" - http://drupal.org/node/11060
