See how it works, now? In the upcoming Quotes List, people can click on a letter (ie. `N`) and it will display all quotes made by people whose last names start with an N. Since you can't index it through the name column (try doing a reg.ex on "Sir General S. Patton" for instance.

) the Letter column is for the search index.
I am guessing you'll now have to fix 27+ quotes in your database?
