I would like a program that will automatically search Craig's list for me with key word searches. Then, when a new ad pops up with that keyword, I would like the program to automatically email that ad poster with a predetermined email of my choosing. I'm not sure how easy this is to do. I know there are other programs out there like this, but I would prefer my own. That way I am not paying for some subscription service. Any help or advice would be appreciated. Thanks!
