How do I remove the stuff behind the .com in your domain in the address bar? example;  website.com/dotnetnuke/info/tabid/55/default/aspx    The stuff highlighted in red is what I'm referring to.

Will this effect my ability to edit or do anything to my website? And what links do I navigate through to get there?

As you may be able to see, I'm new at the web thing. My webmaster has told me in the past that he would have to do something like save the "Notepad" of the website to a file, then redirect it to the domain. Do you have any idea how this is done? Also, Does this have any effect on the search engines or the ability to be found on the search engines?

 Thanks, Jeff...
