LocationAlerter is a handy service that will let you know when your Facebook friends are in town. This free application will let you individualize the people and places that you want to be notified about, and then receive alerts via email whenever any of these individuals is at any of the locations that you are interested in.
In this way, it is very easy to know when any person you have your mind (or heart) set on is at any spot you could approach him (or her) better, or when any friend of yours who was out is back in town.
LocationAlerter is not only a free service, it can also be used without having to sign up for a dedicated profile. Your Facebook account will be used in order to keep track of the activity of your friends, and the email address which is associated with it will be the one employed for the handling of communications.
