Social networking is the way to go, however there is no guarantee that you may be able to signup for a service with a given username, and manually checking username availability on multiple sites could drive you crazy.
Namechk is a new service which will allow you to check if your desired username or vanity URL is still available at dozens of popular social networking sites, regular readers may be aware of a similar service we had written about earlier called User Name Check, which allowed users to find out if a username has been taken on a social networking site.
So the next time you want to signup for a social networking site, go to namechk.com and make sure the username you want is available, rather than filling up the registration form to be told that the username has been taken.
