Can I upgrade my Yahoo messenger?

Can anyone tell how or where to go to to upgrade from old version of yahoo messenger to the new version. Thx?

• I haven't used my yahoo messenger for a long time and I tried to send messenger to my friend. My friend or I can't see each other's messenger. I search in the computer and even look at help but no success. Maybe some computer expert may be able to help me. Another question, I also have skype and I am not able to talk on the microphone. The microphome is a new one and the brand is Altec Lansing which i bought it from Malaysia. I put in the right plug hole and the same colour but still no sound. I don't think the microphone is faulty because it's new. The messenge came out as the microphone is faulty or not plug in properly. Appreciate your help Thanks

• Answer:

  to your messenger question, go to yahoo page, click menu arrow next to y logo at beginning of toolbar (left). on dropdown, click everything yahoo. you'll get an alphabetized page. go to messenger and there is a free download of the newest version. gotta be xp or better, i think
