The Document Foundation maintains a number of mailing lists, on behalf of all LibreOffice community members to facilitate work between a global community such as the one working on LibreOffice. This page lists some of these mailing lists with a link to an archive hosted on this site of the mailing list messages. Please note that some mailing lists might not be archived here. In that case, they will still be listed but will not have a link associated with them.
