Still wondering how to get kata out of beta process...

Intresting kata, but unfortunatelly i get:

ReferenceError: codewars is not defined<:LF:> <:LF:>
throw ex; ^ ReferenceError: codewars is not defined at [eval]:10:144 at [eval]:20:3 at at [eval]:3:6 at Object. ([eval]-wrapper:6:22) at at evalScript (node.js:536:25) at startup (node.js:80:7) at node.js:906:3 

when i try to run tests

It's still showing that this kata has one minor issue in the profile. Can't figure out how can I "close" it. Could you please help me with advice?

I'd suggest adding non-letter characters (i.e. numbers, punctuation marks rtc.) and mention about it in description. This should make kata a little bit more universal :)

Sorry! Thats my first try. I thought this should come from "preloaded" part of kata for both final and example tests.
Updated kata. Thank you.
