What I am trying to explain is that when you select Customize Columns, the window that pops up has two panels.  The panel on the left  clearly defines the only options available that can be used to be added to the right sided panel.  Non of those options work for me.  I want to add "Website".  I am not looking to do anything else, simply to modify the existing options to include website.  As mentioned before, why on earth have 5 columns for addresses?  There has to be a way to add the additional field in the left side panel in order to apply it to the right side. 

Also, 2 other mentions:  1)  It was mentioned that I should be looking at previous answers to my posted questions.  Please be aware I had asked just how does one find them in the first place.  Also, as I read some of the answers this evening, I really don't have any idea what to do as most of it makes little sense to me.
