Here’s a great little tool, that you’ll probably wish you knew about at the start of the internet. namechk has been around for a good few years now, but allows you to check to see if your desired username or vanity url is still available at dozens of popular Social Networking and Social Bookmarking websites. This is a brilliant way to start tying in your brand (or personal brand) consistently by registering a username that is still available on the majority of the most popular sites. It really is simple. All you need to do is throw in the username of your choice and namechk will search through over 150 different sites to see if where your chosen username is available.
