+        ### Prefer using the discussion boards
+        
+        If your question or suggestion may result in a longer discussion or the answer may interest others, it might be a better idea to open a topic [in one of our discussion forums](https://github.com/orgs/projectM-visualizer/discussions).
+        
+        Questions answered in the boards can be marked accordingly and others may find it easier than by searching through closed issues.
