Config Questions for EasySocial

I have a few questions regarding EasySocial:

1) What is a Story Form?
2) I only want certain user groups to be part of EasySocial. I have enabled "Exclude Site Admin's Stream From Appearing" which excludes our super admins, but I also need to exclude our Manager group. Is there a configuration setting for this, or do I need to manually remove the Managers from the Users area?
3) When a user bookmarks an item, what does this mean?
4) When a user pins an item, what does this mean? I see that it gets posted in the user's Profile, but does it get posted to the top above all other posts?
5) How do I remove certain items from the Edit Profile page, such as Gender Birthday, Website, etc.?
6) How do I remove the People/Location/Mood icons that display when I create a post?
7) I will have only one Profile Type for EasySocial - Alumni. Is there any way to remove this profile from the Share section when creating posts? Since Everyone and Alumni are the same, I don't want to confuse users.

Thank you.
