+We appreciate issues as very valuable contributions, but just to make sure here are things that are important to do before filing an issue.
 
-* Only report issues (and perhaps request new features, FEATURE):,Usage Questions should be asked on [Jackson-users](https://groups.google.com/forum/#!search/jackson-users) list -- you are more likely to get help that way (and we will promptly close questions-as-issues)
-* Check to see if this issue has already been reported (quick glance at existing issues): no deep search necessary, just quick sanity check
+First, and foremost: THIS IS NOT A GENERAL-PURPOSES SUPPORT FORUM FOR ASKING QUESTIONS.
+For questions you will instead want to use one of these resources
+
+- https://groups.google.com/forum/#!forum/jackson-user
+- https://gitter.im/FasterXML/jackson-databind
+
+so please go there for anything other than bug reports and feature/improvement suggestions.
+You are more likely to get help that way (we will usually close questions-as-issues)
+
+We would also appreciate if you:
+
+* Check to see if this issue has already been reported (quick glance at existing issues)
+    * no deep search necessary, just a quick sanity check
 * Include version information for Jackson version you use
 * (optional but highly recommended) Verify that the problem occurs with the latest patch of same minor version; and even better, if possible, try using the latest stable patch version
-    * For example: if you observe an issue with version `2.4.1`, first upgrade to `2.4.6` to ensure problem has not already been fixed.
+    * For example: if you observe an issue with version `2.9.3`, first upgrade to `2.9.9` to ensure problem has not already been fixed.
+
+With that, let's hear what problem you are having & thank you in advance for reporting it!
