There are various games and applications available that can be accessed via the conversation window by clicking the games icon and challenging your current contact. As of April 18, 2014, games were removed from Yahoo Messenger.
Yahoo's software previously allowed users with newer versions (8 through 10) to use webcams.
This option enables users from distances all over the world to view others who have installed a webcam on their end.
As of December 14, 2012, the interoperability between Yahoo Messenger and Windows Live Messenger ceased to exist.
The Live Messenger contacts will appear as greyed out and it will not be possible to send instant messages to them.
Microsoft has also had talks with AOL in an attempt to introduce further interoperability, but so far, AOL seems unwilling to participate.
