This plugin provides thirteen handy template tags that relate to the index/position of a post within a loop’s listing of posts.
Some of the template tags provided by this plugin relate to the position of the current post within the current loop:
<ul>
<li><code>c2c_is_first()</code></li>
<li><code>c2c_is_last()</code></li>
<li><code>c2c_is_at_index()</code></li>
<li><code>c2c_is_even()</code></li>
<li><code>c2c_is_odd()</code></li>
<li><code>c2c_get_the_index()</code></li>
<li><code>c2c_is_index_within()</code></li>
<li><code>c2c_the_index()</code></li>
</ul>
Other functions help you get a post (or posts) at a given position in the current loop:
<ul>
<li><code>c2c_get_post_by_index()</code></li>
<li><code>c2c_get_posts_by_index()</code></li>
</ul>
While the remaining three functions relate to index information about the loop in general:
<ul>
<li><code>c2c_get_last_index()</code></li>
<li><code>c2c_is_post_in_loop()</code></li>
<li><code>c2c_is_valid_index()</code></li>
</ul>
Please see the Template Tags section (in some places found under the Other Notes section) for descriptions of all the functions and their arguments.
Note that index counting begins at 0, which means the first item has an index of 0. An index of -1 indicates no posts were found.

Custom Excerpts allows you to implement custom excerpt text, length, and to choose HTML tags to allow and whether to make the link nofollow or dofollow. Previously the only way to achieve this was to edit the WordPress core file formatting.php which meant changes would be lost after each update.
