Shows word and sentence counts plus a readability analysis of the post 
currently being edited using three different readability measurements.
Readability analysis is an attempt to show how difficult a text is to read. 
There are several methods of doing readability analysis. The most popular 
methods are used here. The Flesch and Flesch-Kincaid methods use formulas based 
on the average number of words per sentence and the average number of syllables 
per word. The Gunning-Fog method uses a formula based on the average number of 
words per sentence and the percentage of “hard” words (words with 3 or more 
syllables) in the passage.
Both the Gunning-Fog and the Flesch-Kincaid give a score that is the number of 
years of education the reader must have completed to understand the text. 
Different types of writing calls for different scores. Technical subjects may 
require a higher level of education so a higher Fog or Kincaid score is 
acceptable. Informal writing may try for a score in the 7-10 range. The Flesch 
score is a percentage. The higher the value, the better the readability.

With the Custom Pagination plugin, a user may customize the look of a post’s next and previous links using the HTML editor. It is built by <a href="http://webit.ca" rel="nofollow ugc">WebIT.ca (Dimitry Zolotaryov)</a> and funded by <a href="http://datedaily.com" rel="nofollow ugc">DateDaily.com</a>: an online dating and relationship blog.
The link is created by selecting the text label within a post’s body and clicking the link icon. In the Link URL field, the following values will produce a link to another page:
<ul>
<li>page:next links to the next page</li>
<li>page:prev or page:previous links to the previous page</li>
<li>page:first links to the first page of the post</li>
<li>page:last links to the last page of a post</li>
<li>page:n links to the nth page of a post (e.g. page:2 for the second page)</li>
</ul>
If link is directing to a page that does not exist — for instance page:next on the last page –, the link and the link text do not appear.
All links processed by Custom Pagination will have the added class name ‘page’. If you wish to style such links, in your CSS, add the line:
<pre><code>a.page { /* page style goes here */ }
</code></pre>
