There are certain times when you want to know the exact moment when a buddy logs into his or her messenger and here you’ve found the solution. Detectinvisible.com offers some great Yahoo tracker services. You can check the real yahoo status of someone but you might want to spy on your buddy when he or she logs on to messenger. Don’t know how to do this? Well, it’s quite hard to sit in front of the monitor all day and keep on checking the ID you want to spy on and you might also bump into some security filters and get your IP blocked and banned.
The solution is easier than you think though because everything comes down to spying on a certain ID and alerting you though your email when the ID logs on to messenger. We have called this service Yahoo ID Alert and we really recommend it if you want to know the exact moment when your buddy has signed in to Yahoo messenger, without the hassle of permanently checking him on the website.
