Just last November, Yahoo introduced Yahoo Messenger that was integrated with Yahoo Mail Beta at the Web 2.0 conference.  At the time, it was just a preview, but now Yahoo is ready to roll it out to users.  They started this process yesterday, but not everyone will get it at once.  If you don’t have it already, you should have it soon.

This is such a no-brainer integration that many Yahooers will be happy with.  At the top of your Yahoo Mail Beta, you’ll notice, the online/offline presence indicator. When you are logged in, and available, you’re able to see which of your contacts are online in the left panel of your inbox. If any of your contacts are online, you can just click to start a conversation with them, which will open in a new tab.

You’ll find the tabs up at the top of the screen.  The messaging within the Mail is complete with conversation bubbles and avatars.  Additional instant message conversations would appear in  tabs up at the top.  If you had three conversations going, you’d have three separate tabs for each of them.

With the tabbing, it will be easy for you to switch back and forth between Yahoo! Mail Beta, and Messenger. Another nice feature is that with one click, you can take a conversation you just had in messenger and convert it into an email.  The whole conversation would be displayed within your email.
