Clarification on Announcements feature -

This is not a problem. I just need clarification on an option.

I am looking at the Announcements feature on my site and reading the documentation on it here:
http://stackideas.com/docs/easysocial/administrators/announcement/annoucement

Documentation does a good job of explaining how it works but I'm confused about the difference between Broadcast to All Profiles vs Registered Users.

I take it the all profiles option includes other members with admin privileges and users option means non admin members?

Do clarify it for me.

Thank you.
