Hey, guys!
I'm not sure, but seems like your rest API is broken

curl "http://www.codewars.com/api/v1/users/R1ZZU"
{"data":[{"id":"5313b713bb244a0eb20001fe","name":"Number-like counter","slug":"number-like-counter","completedLanguages":["javascript"],"completedAt":"2014-11-08T21:33:35Z"},{"id":"544675c6f971f7399a000e79","name":"Convert a String to a Number!","slug":"convert-a-string-to-a-number","completedLanguages":["javascript"],"completedAt":"2014-11-08T21:31:45Z"},{"id":"52ed326b8df6540e06000029","name":"Simple elevator","slug":"simple-elevator","completedLanguages":["javascript"],"completedAt":"2014-11-06T20:12:45Z"},{"id":"514a677421607afc99000002","name":"getNames()","slug":"getnames","completedLanguages":["javascript"],"completedAt":"2014-11-06T19:53:27Z"},{"id":"53a8a476947277a3020001cc","name":"Array Appender","slug":"array-appender","completedLanguages":["javascript"],"completedAt":"2014-11-06T19:51:39Z"},{"id":"52ab60b122e82a6375000bad","name":"Sort Santa's Reindeer","slug":"sort-santas-reindeer","completedLanguages":["javascript"],"completedAt":"2014-11-06T19:49:01Z"},{"id":"53f1015fa9fe02cbda00111a","name":"Color Ghost","slug":"color-ghost","completedLanguages":["javascript"],"completedAt":"2014-11-06T19:24:02Z"},{"id":"50654ddff44f800200000001","name":"Broken Greetings","slug":"broken-greetings","completedLanguages":["javascript"],"completedAt":"2014-11-06T19:09:39Z"},{"id":"50654ddff44f800200000004","name":"Multiply","slug":"multiply","completedLanguages":["javascript"],"completedAt":"2014-11-06T19:07:14Z"}]}

As you can see /users endpoint returns data which not contains user name, honor etc.
