While upgrading Open GreenMap from Drupal 5 to Drupal 6, we had to port the Taxonomy Limit module by codexmas, which restricts the number of taxonomy terms which can be chosen for a multiselect vocabulary. The author hasn't had time to create his own Drupal 6 version, so we at Openflows Community Technology Lab volunteered to become co-maintainers. The new Drupal 6 version of the module is now available, which also fixes a few small bugs from the issue queue. Most importantly, since the Open GreenMap site is available in English, Spanish, Brazilian Portuguese, and German (so far) we made the module's error messages translatable using multilingual variables (see README.txt for details). Enjoy!
Future plans for the module include adding a feature to also limit the length of a freetagging taxonomy term to a set number of characters, since it's been requested by a few users and no other module currently provides this feature. We look forward to being able to contribute this to the community.
