I'm proud to announce the newest contributed module on http://drupal.org. It's called Taxonomy Share, and is used to import a full taxonomy from one site to another. The path to my new project is http://drupal.org/project/taxonomy_share.

What can Taxonomy Share do for you?

If you have two (or more) sites that you would like to share vocabularies between, this is an easy, light weight module that can assist you in importing the vocabulary from one site to the other. I hope some developers find this useful in their projects along the way.
