We all need a username for login purposes for almost every site. Finding a cool and catchy username is not easy. We want a username that will represent our personality somehow because we never know that in the future our username might get popular.
But what if we have a username in mind and we want to check its availability acrosss multiple websites?
Username Check is a simple website that lets you check username for more than 50 sites. Ranging from email providers to social networking site. It has got almost every important site listed e.g. Gmail, Technorati, My Space, WordPress, YouTube etc. You just have to put in your desired username and the service will check its availability on the fly.

The site runs on an application that pings the site with your desired username. The site uses Dojo as it does all the checks using Ajax. Each check takes a couple of seconds using Ajax, so you don't have to wait for the page to load.
Check your username now and see whether it is taken or you still got luck.
