This project is mostly meant as my initial attempt at making Property Editors for Jupiter (Umbraco CMS v5).
The I18N Selector I've made makes it possible to select a Region/Language or a Timezone. As the schema of documents and members, users etc. are the same in Jupiter, this will make it possible to let the users/members select their prefered language, region and timezone.
The "package" is actually a simple ZIP file that should be unpacked in the /Plugins/Packages folder of Jupiter CTP.
