Check if a username is Available - Namechk Program - Great tool

I have just come across this awesome little tool while reading a post on Blogger Institute. This little tool is called Namechk and basically what it does it helps users check availability of user names on 112 different Social Networking and Social Bookmarking websites at the same time without having to leave their site. Looks something like this.

I would say that it helps a lot if you are a busy person and do not have the time on your hands to log on over a 100 sites and then check if the name you want is available!
