Unfortunately, this is not such a great idea. The average person has a vocabulary of between 2000 and 5000 words (i'm not totally sure about those numbers, but i'm on the same order of magnitude). So assuming you can use up to 5000 words and make things easy to remember (which is the whole point), that gives you a search space of 25,000,000. That would be crackable minutes. Add on two random digits increases the search space by a factor of 100. That gives you 2,500,000,000 passwords to check, which is checkable in an hour or two at the most.

Bottom line is, dictionary words never make secure passwords. English text only has about 1.5 bits of entropy per letter. At work, we strongly discourage our users from using dictionary words from any language

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
