The 3 easiest ways to post advertisements into your sidebar are as follows:
WP Now Ad Widgets Each theme has a designated Advertisement widget titled either WP Now Ad Spot or WP Now: Banners.   Add this widget to the sidebar wherever you would like it to appear.  In the Theme Options Panel (located under Appearance in admin),the first Ad Code field is for the sidebar Ad widget and will either be a 125x125, 250x250 or 300x250 size depending on the theme.  Simply enter your code into this field.

Text Widgets Enter any ad code into a text widget.

Non-Widget Sidebar Ads If you wish to display advertisements in the sidebar, but not as a widget, open Sidebar.php and paste the ad code in directly above or directly below.

1) Create a new category titled Featured or something similar.

2) In admin, navigate to the Theme Options Panel located under Appearance.  Locate the drop-down menu under Featured Category. Select "Featured".

3) Any posts you want shown in the Featured section, just assign it to the Featured category.

To setup the featured posts section you need to add the following to the Custom Fields on your post page:

*You can use the WP Post Thumbnail Plugin to create the specific image sizes and insert their URL in to the Custom Fields automatically. Click here to view a tutorial on using the WP Post Thumbnail plugin. You can also insert the information manually by uploading each image size. For image sizes, please see the Common Image Dimensions FAQ for your particular theme.

To Determine which Posts are Displayed in the Featured Section:

1) Create a new category titled Featured or something similar.

2) In admin, navigate to the Theme Options Panel located under Appearance. Locate the drop-down menu under Featured Category. Select "Featured".

3) Any posts you want shown in the Featured section, just assign it to the Featured category.

The Featured Video shown on many of our demos is simply a text widget with embed code added.  Please be sure to change the video size so it fits within the sidebar.

Navigate to your Theme Options Panel (located under Appearance in admin).  Find the Advertisement section, simply paste your code into the specified fields and click save.

Sign up at http://www.gravatar.com with the email address that you've associated in your blog with your user account, and upload your image to gravatar.com. After you've done that your gravatar.com image will appear whenever you post on your own blog.  This photo will also appear when you post comments on other Wordpress blogs (if you use that email address in the mail field of the comment form).

In Wordpress Admin, navigate to: Appearance -> Widgets.   Drag the widget titles from the lists on the left side to the "Sidebar" sections on the right side.   You can also drag and drop the widgets up or down within each Sidebar to change their placement above or below other widgets.
