Description

Some campers found the "We underestimated you" congratulatory line to be inappropriate. I removed it and added a few new ones.

LGTM.

Quick query: Where do we plan to use the calls-to-action ?

Thanks @QuincyLarson

[QuincyLarson]

@raisedadead We may start letting campers turn on browser notifications to remind them to come back and code. Like once a day a noon, it could pop up a browser notification that takes them back to their current challenge. This feature is just an idea at this point, but I didn't think it would hurt to add my proposed call to action phrases to the document.

[raisedadead]

Oh yes, totally. I was just curious about the addition. 😃 !

@raisedadead thanks for QA'ing this.
