Go to Appearance > Widgets and drag a text widget into the Skin 2 Home Page Widget area that you created.
In the text widget use a [blog] shortcode for your content:
[blog category="999" images="true" image_width="40" image_height="40" post_content="excerpt" excerpt_length="23" show_date="false" author_link="false" comments_link="false" show_category_list="false" show_tag_list="false" posts_per_page="3" paging="false" orderby="date" order="desc"]
Save the text widget, and that’s it.
I have used the category ID “999″ in the above shortcode, you must replace this with whatever is the ID for your recent news category.
P.S. Instructions for including code in posts are here: http://para.llel.us/support/groups/mingle-wordpress/home/
