There are also a few things about Yahoo! Messenger 9.0 Beta that you may not know about. One is that 9.0 is the first version of Messenger that is unicode compliant. This means that it supports IMs and status messages in many more languages than before.
A few other interesting tips& 9.0 will remember your status between sessions. So if your status on a Saturday night says Partying like it's 1999!, be sure to change it when you get to work on Monday. Also, if you have both a Yahoo! and a Windows Live ID for a friend, your friend will appear in your contact list only once. To IM your friend on the Windows Live network, click the drop down arrow next to the IM button below their name when you hover on them.
And lastly, if you usually show both online and offline contacts in your list, you can set a preference to bold your online contacts to help distinguish them. You'll find that preference under Messenger > Preferences > Appearance (Show online contacts in bold text).
