+<h3>FAQ: Why did you change the wordlist?</h3>
+
+I used to use <a href="http://world.std.com/~reinhold/diceware.wordlist.asc">the original wordlist</a>,
+but it contained a lot of symbols, punctuation, numbers, and 2 and 3 letter words.  I wanted to try a different
+wordlist with longer words, no non-alphabetic characters, and words more commonly used.  So I got
+<a href="https://github.com/first20hours/google-10000-english">the 10,000 most commonly used words</a> in the 
+English language from <a href="https://books.google.com/ngrams/info">Google's Trillion Word Corpus</a>.
+</p>
+
+I am always considering what words I use in the wordlist.  With the current wordlist, I noticed that
+some words are really long, and this could also be an issue.  I may investigate using a wordlist of
+shorter words in the future.
