+# Temporarily Not Accepting Issues
+
+March, 2019
+
+Pull requests are still welcome.
+
+We've had trouble recently with people refusing to follow the [Issue
+Templates](/~https://github.com/paper-trail-gem/paper_trail/tree/master/.github/ISSUE_TEMPLATE).
+
+Issues are temporarily disabled while we discuss, as a team, how to handle
+this problem.
+
+Unfortunately, GitHub does not seem to offer a way of disabling the *creation*
+of new issues without also hiding existing issues.
