If anyone in the country posts an ad on Craigslist with any one of those words I am notified about it and I am going to explain how I do it.
It's actually pretty easy.
1st make sure you have a Gmail account, so that in turn you have a Google drive account.
2nd join this site ifttt.com
3rd watch the video to see how to set up a recipe here,
That's it. It's pretty easy.
I hope this helps some of you out.
