+    as a player. Don't simply put "latest" or we will ignore it.

+    https://gist.github.com/, then paste a link to them in the relevant parts
+    of the template. Avoid using Hastebin or Pastebin, as files are deleted
+    after a period of time.

+4.  If you are reporting an issue with messages or in-game behaviour, please
+    include screenshots detailing the problem.
