The more tag is a little gimmick that you can add onto your posts. It is a link that allows the reader to continue reading the remainder of the post on another page.
It is particularly useful for keeping your posts tidy, especially if your blog has the newsroll on its first page, and your posts have a tendency to be very long. Some people don’t mind showing all of their long posts, whereas others might want only to present only a taster paragraph with a more tag after it, as a link to the rest of the post which is housed on its permalinked page allocated to it by WordPress.
Here is a fancy example of a more tag from my other blog:

But WordPress.com provide a nice simple example for you to use (see the example at the bottom of this post). This is how you add in a more tag: first go to your Dashboard (via http://BlogURL/wp-login.php and than add in your username and password):

Click on ‘Posts >Add New’ to bring up the post editing page:

Type in all of your post. Remember that your first paragraph, or however much you want to be seen before the more tag, should be enticing and informative to encourage your readers to click on. If you are too ambiguous or cryptic, then the opportunity might be lost – give them a reason to want to read more, even with a call to action!
Next place your cursor immediately after the paragraph you want to be visible from your blog page, and click on the more tag icon:

This is where you’ll find the more tag icon:

And automatically the more tag will be inserted (it looks like a line with the word ‘more’ on the right):

Don’t forget to leave a return-space after the more tag, or your paragraphs will be bunched up. Once you’ve finished writing your post, then you can publish by clicking the ‘Publish’ button:

Then to view your more tag, visit your blog by clicking on the name of your blog at the top:

And there is the ‘Read the rest of this entry’ link after your introductory paragraph. Click on it to go to the permalinked page to read the remainder of your post:

Enjoy using more tags in your blog!
