A couple of things:

1. Any possibility of including multiple select for lists or categories?

2. While I am at it, the project page says -

If the cron is set up to run every hour, the craigswatch module will scan the first 100 postings (the first page) of the craigslist page for "US nevada las vegas for sale cars+trucks" listings. It will then filter out any listings that contain the words "honda" and "accord" and create a listing record for the user.

Does this mean that many of the same listings could be repeated every hour?
