Login into multiple Yahoo ID at the same time in messenger

Most people have more than one Yahoo ID and would like to use both at the same time in yahoo messenger to chat. However, by default when you install Yahoo Messenger 8, 9 or 10 can only be accessed with a Yahoo ID at a time.
If you have multiple yahoo account and would like to go for that, they have no choice but to Sign Out account and access other id. I'll show you a little trick that will allow you to log on to yahoo with multiple ids at a time. No software or any third party application. All you have to do is make some changes in the Windows registry.
