(Not sure which forum to post this question.)

Is there a website or application that will save a multi-city international search so I don't have to enter it daily to see if seats have opened up.

E.g., I have miles that can be used on Star Alliance partners, and, at the moment, no low-mileage seats are available for the flights I want. But I suspect seats will become available closer to flight time -- and I'd like a way to automate the search process.

Any suggestions (preferably free ones)?
