Sharing Content Across APAN

Sharing content is probably one of the most important things APAN offers.  I've recently found out that you can't just go around randomly sharing content with everyone. APAN settings, by default, sets a users profile for private messages to none.  If you want to share content the users you are attempting to share with must opt in to sharing (sending a private message) and they must activate it in their profile settings. 

Receiving private messages should be set to Colleagues Only or Everyone to take part in this.   What is critical to know is that you can turn this on to collaborate during a set period then turn it back off when needed.
 
So, if you aren't sure why you can't send that awesome blog post to your colleague, friend or coworker, its because they've opted not to share, or left the default setting at none.
