One morning I got that email and I no longer had an excuse :D
I like what you did there, great stuff! I do wonder how many personal bots are out there, scraping sites for individuals' own gain like this.
I remember a good few years ago, getting frustrated at having to wait six weeks for a driving test. I wrote a little script that ran every half hour, logged into the DVLA's site (in the UK), entered my details, and looked for recent cancellations. If it found one, it sent me the details, and I'd madly scrabble together to try and book the slot. After I failed my first test, it was even more useful :)
It was beautiful, transitioning from sifting through CL by hand, to having carefully filtered ads delivered to my inbox within an hour of being posted.
