Hi @jmartinez,
I've merged my colleague's edits to the master branch for this notebook and have committed my own edits as well. Please note a couple of things: the words suscribe/suscription showed up throughout and my colleague and I both believe you meant "subscribe/subscription" (a 'b' after the 'u'), so we've changed these throughout (including where I saw in the code), but there are images that still include the suscribe/suscription words. Please update those images if necessary.
Once you've reviewed my edits, agree with them, and updated the images, please merge the "shiny_edits" branch with the master.
Thanks!
