If you’re a fan of Yahoo! Messenger, you’ll love the web-based version. For now it’s just a BETA version, but it works great! It’s very easy to use and it has a really cool Vista-like appearance. It works on any browser (at least that’s what they say) and it can also be used to IM Windows Live contacts. Click here to start using it. Have fun!
