A second 'promotional' column to the right of EasyBlog?

Hi,

I'd like to have the post content take up the left two-thirds of each blog post page, and have a 'promotional' column on the right-hand side.

A promotional column is considered by many to be an essential best practice for blog sites. It can contain call to action buttons, a sign-up area for the website's email newsletter (very important!), recent blog posts, etc.

Please see attached example.

Is there any way to do this with EasyBlog?

Thanks,

Douglas
