Scheduled posts are never shown

A Great Plugin.

As I am very new to wordpress, so asking you this simple question.

I am trying to use my blog like a monthly magazine style. So, I created a parent category, say FEB2015 and then actual categories of the magazine. Now, I add posts under FEB2015 and also choose a sub category.

Then, I am using a sidebar widget ‘BNS Featured Category’ and showing all posts’ titles from FEB2015 category in this sidebar widget.

Now I want to use this Intelliwidget to schedule all the posts which I am writing during January 2015, but don’t want to display them until 1st February 2015.

Please explain me in steps:
1. Do I need to save my post as a draft pr publish it?
2. What boxes do I need to check from the 5 boxes of Include, Exclude in Post Selection?
3. Any other setting do I need from General Setting, Post selection and/or Appearance?

Thanks & Regards,
Mahmood
