+Unfortunately libravatar is being shut down on 2018-09-01

+This is used in the comments plugin to get an avatar url.
+
+It would probably be best to remove the code that tries to use it, in case
+its dns eventually gets taken over by something that causes some kind of
+problem. (The shutdown page doesn't say what will happen to the DNS.)
+
+It might also be a good idea to filter out avatar urls in existing comments
+that point to libravatar.org. --[[Joey]]
