+
+            Thank you for contributing to the Opencast Editor.
+
+            We noticed that you have not yet filed an [Individual Contributor License Agreement](https://www.apereo.org/licensing/agreements/icla).
+            Doing that (once) helps us to ensure that Opencast stays free for all.
+            If you make your contribution on behalf of an institution, you might also want to file a
+            [Corporate Contributor License Agreement](https://www.apereo.org/licensing/agreements/ccla)
+            (giving you as individual contributor a bit more security as well). It can take a while for
+            this bot to find out about new filings, so if you just filed one or both of the above do not
+            worry about this message!
+
+            Please let us know if you have any questions regarding the CLA.
