The page "Links to our Community" ( https://devonfw.com/website/pages/docs/further-info-community-links.asciidoc.html ) has to be adjusted regarding external users, as Yammer is only accessible for users from within Capgemini. The infos for internal users should be moved to a snippet. Also the supposed contact E-Mail [email protected] is a technical email address and has to be replaced by a more reachable email address.
