How come when I sign on to yahoo in the invisible mode, people can still se me online?
Well if you sign in as invisible people can know if you’re online by your status in other sites, for example, if you have a 360 it will have your status as Online. To fix this in messenger, click on the tab Messenger > Privacy Options On top where it says “when i sign in Yahoo! Messenger…” uncheck the box “Allow Yahoo! web sites to sho when I am online” that may fix one reason how they may find out your online. Another reason may be your friends have some kind of software that can show whether users are online or offline for real, but unless you know your friends to be into “add-ons” that may not be the case. Try it and see where it gets you. Hope that helped!
