How about considering making a public Outsystems badges widget that we can add to our websites and signatures to promote both Outsystems and our community involvement? A bit like that shown in our profile where it displays the 4 most important (ie certifications) and then lets the viewer click to see our public profile. This is a great way to promote and verify our certifications and adds extra exposure for Outsystems at the same time.
If it was a simple <IMG & link it would be easy for someone to embed in their websites and email signatures. Also allowing and encouraging those who want to use old fashioned business cards to display the badges would be a good idea.
