+
+ ## Proposal
+We want to solve the issue described by baudry in #916.
+"Check that all PR submitted for the course come from a Github id that corresponds to one KTH id of a student who registered for the course"
+
+ ## Proposed solution:
+
+* Create a GitHub javascript action to be run on each PR.
+* Extract the GitHub id of the PR author.
+* Create a list of valid kth ids (from students registered to course).
+* If GitHub id matches kth id, approve PR.
+* Otherwise, check that the Member mail address in the README match.
+* Utilize Status checks API to visualize the result.
