I'm looking for an application that would notify me of postings on CraigsList. Preferrably something that would pop up a message, or some kind of a counter like Mail app when it gets a red dot with number of new emails. Some of the options that I need is for the app to display the direct link to the listing, or some kind of an email notification, and also some word filtering. I tried notify.me, but its app doesn't seem to work, and filtering doesn't either. It does email me, but the Google email notifier can take a while before it checks mail again, so I'd like something that can check every 5-10 minutes. Anyone know how I could do this, and with what app?
