Check if your username is available

UserNameCheck.com allows you to easily check if your desired username is available on many of the popular social websites.

After testing some of the sites aren't reporting back properly and say a name is available when its not. Try it for yourself and see what results you get. It did tell me my username was available on a site that it was recently not and I was able to grab it.
