+    Hi Magnus,
+
+    I'm just going through the source code and assets to check licensing.
+
+    Can you confirm that you're willing to license your contributions
+    under the GPL 2.0? You'll still hold the copyright on your
+    contributions.
+
+    You can read the full text of the license here:
+    https://github.com/TheJosh/chaotic-rage/blob/master/LICENSE
+
+    If you are happy with that, can you please reply via an email stating
+    that fact, something like this:
+
+        All of my past & future contributions to Chaotic Rage may
+        be licensed under the GPLv2 license.
+
+    Thank you for all of your contributions!
+
+    Cheers,
+    Josh

+    I thought the licence was already GPL 2.0, so I have no problem with the

+    under the GPLv2 license.

+    Hi Mats,
+
+    Many years ago, you produced a few songs for a game I'm working on
+    called "Chaotic Rage".
+
+    The songs are:
+    - An Introduction to Pain
+    - High Speed Kill Greed
+    - Pump Action Interaction
+
+    I just wanted to confirm that you are okay if I distribute those songs
+    as part of the game, and licensed under a GPLv2 license. You would
+    still retain the copyright.
+
+    If this is the case, can you please reply to this effect.
+
+    Cheers,
+    Josh
