Gravatar stands for “Globally Recognized Avatar” where an avatar can be a picture of yourself or a cartoon/logo/image which represents you or your business as shown on the left. By now, you would have noticed pictures or cartoons alongside blog comments. These are the avatars of blog visitors who maker their comments on gravatar enabled blogs
How does it work?
For avatars to appear beside a visitor’s comments, the Wordpress blog must have a Gravatar plugin installed or are gravatar enabled.
If you want to place your own avatar alongside your comments in blogs that are gravatar enabled, you need to sign up for a free account at Gravatar.com.
During the sign up process, you would be required to provide an email address and upload a picture (avatar) to the site. The size of the avatar image would normally be 80px by 80px. The picture will be stored on the Gravatar.com server and associated with your email address.
Thereafter, when you make comments on any gravatar enable blogs by providing your email address which matches the one stored on gravatar.com server, your avatar will appear beside your comments.
If you love to see your picture to appear on blogs around the world wide web, all you need to do is to sign up for a gravatar.com account and make comments on any gravatar enabled blogs.

Knowing how to hide wordpress pages from the header horizontal navigation menu is useful especially when you:
1. have a number of pages and do not want to clutter the navigation menu with your page titles.
2. want to create a special page for the purpose of linking from your posts or other pages.
Below is a way to hide unwanted page links from your navigation menu:
1. Go to your Wordpress Editor (Appearance section) and open the header.php file and look for the following codes:
<?php $children = wp_list_pages(’sort_column=menu_order&depth=1&title_li=’);?>
2. Add the following codes (in green) and page IDs (in blue) that you want to exclude from the navigation menu as follows:
<?php $children = wp_list_pages(’sort_column=menu_order&depth=1&title_li=&exclude=1,2,3‘);?>
Header.php codes in different themes may look different as shown in the example below. In this example, add the codes (in green) and page IDs (in blue) in the manner shown below to exclude the page links:
<div id=”navigation”>
<ul class=”nav”>
<li id=”<?php if (is_home()) { ?>home<?php } else { ?>page_item<?php } ?>”><a href=”<?php bloginfo(’url’); ?>” title=”Home”>Home</a></li><?php wp_list_pages(’title_li=&depth=1&title_li=&exclude=1,2,3‘); ?>
</ul>
</div>
Note: The page IDs 1, 2,3 is for illustration only. Click here to learn how to get the actual post or page IDs.
With this knowledge, you will have a much wider selection of Wordpress themes that you can use as most of them have horizontal page menus.
