As I said, i am going to list all the cool sites that Ive found on internet so far. So, here’s another one of them. Consider this more as a utility site rather than anything else. So what is it about? Well, detecting invisible users on yahoo messenger wasn’t really tough, but it wasn’t easy either ! Here, all you have to do is go to this site, enter the ID of the person, and it finds out his or her or its status 
.So for the people who have always felt that someone has been ignoring them on yahoo, but were never sure about it, this is for you only 
PS:
- Don’t ask me how or why i found it .
- It doesn’t use your IDs for mailing spam messages, i have checked that.
