Sometimes it just seems like too much bother to log on to Glow, click the blog tile and then navigate to your dashboard before finally clicking the + to add a post. This can be time consuming for young pupils too. 

To make it quicker you can link, in a widget on your blog, to the New Post pages, this will take pupils through the log on page and land them on the New Post page if they have permission to do so.

This is how you do that. Make a New Text Widget

Navigate to the Widget Page on the Dashboard: Appearance->Widgets
Add a Text Widget a sidebar
Add the following code to your widget.

<a href="/nl/bantonbiggies/wp-admin/post-new.php">
Add a new Post
</a>

note you could use the full URL to the Add Posts page or follow the example above:
start the URL with a Slash, the LA code, a slash and your blog slug. followed by /wp-admin/post-new.php

The above example will look like this:

Add a new Post

But that one will not work for you unless you are in Banton Primary p5-6-7.

NB, bonus tip, the code above is produced using the SyntaxHighlighter Evolved plugin.
