When I present my workshops on social media marketing, I always urge attendees to secure their Twitter username ASAP, even if they are not sure whether they will ultimately tweet.
Twitter usernames must be 15 characters or less, and many desirable names are still available. You can sit on your acquired name for 6 months, without posting a single tweet. (After that your unused name gets sucked back into the Twitter username pool and released to the general public after an additional 6 month's time in no man's land.)
But what if you are launching a comprehensive social media marketing campaign? You might want to check if the same name is available on Blogger, Twitter and Linkedin before you even get started. Now there is a quick and easy way to check username availability simultaneously, in a matter of seconds, on a super useful website with the catchy name UserNameCheck.com.
The User Name Check website is very spare. There is a search window, followed by a massive list - 4 columns of dozens upon dozens of social media and other websites, from flickr, to livejournal, to posterous, and much, much, more. All you do is enter your desired name in the search window, and click "check". Then sit back and watch as one after the other, in a matter of seconds, you find out if your username is available or unavailable on that specific site.
Even better, if, for example, your Twitter name is listed as "available", you can click on "available", and you are taken directly to the Twitter website where you can sign up on the spot.
One stop user name shopping.
