Hector  awesome! Are you cool w me changing the name of this to doand assigning it to Issac?

Hector - ADDED

Thank you Isaac!
Christina, 
Changing the name? I have already created the GTM tag. Isaac had to add the Code to the site (which he already did). I take care of all the other things involved in it. Him and I have a system in place that works out pretty well so we are good. 

For documentation purposes- We probably shouldn't edit a "to do" rather we can add a new "to do" or keep the conversation going. and especially never delete a completed todo - archive is okay. I hope that makes sense Christina  

I agree Whitney. 
We would be going crazy looking for the original one wondering where it went. 

This is ready and set!
