I just signed up for gitter and joined the channel.

Awesome! Thank you! I appreciate all of the feedback!

I will do that once the validation process is done. That being said, I am new to creating katas. What would be the best way to go about restricting built-in functionality? Or would this be better suited as a lower rated kata? I won't have much time to modify this kata until later today, but I would like to get this kata working properly if possible.

Thanks for the feedback. I will modify the problem as soon as I can.
