+ * NewUsersList parser hook extension -- adds <newusers> parser tag to retrieve
+ * the list of new users and their avatars.
+ * Requires SocialProfile extension in order to work correctly.
+ * Works with NewSignupPage extension, i.e. if the user_register_track DB table
+ * is present, this extension queries that table, but if it's not, then the
+ * core logging table is used instead.
