There are a number of ways to get support for Cargo, including questions, suggestions, bug reports and feature requests:
- Place questions on the discussion page for Cargo.
- You can submit bug reports and feature requests at MediaWiki's Phabricator site, here; enter "MediaWiki-extensions-Cargo" as the project name. (The current list of known bugs and requested features for Cargo can be found here.)
- Use the Semantic MediaWiki mailing list, semediawiki-user.
- Use the main MediaWiki mailing list, mediawiki-l.
Which mailing list you use will probably depend substantially on whether you are already an SMW user. If you use either mailing list, please add "[Cargo]" at the beginning of the subject line, to clarify the subject matter.
Translation of Cargo is done through translatewiki.net. The translation for this extension can be found here. To add language values or change existing ones, you should create an account on translatewiki.net, then request permission from the administrators to translate a certain language or languages on this page (this is a very simple process). Once you have permission for a given language, you can log in and add or edit whatever messages you want to in that language.
