Which site/app/service are you referring to? If you mean an account here, it's not to have your own website, but only to have a more personal experience of the Mobile Nations sites (less ads, too!) and, for the forums, to have a better way to follow up on your threads, posts that mention you or something you wrote, etc. Plus, it gives us a chance to know you better (like knowing which devices you post more about or issues you've had in the past, etc.).
