URGENT : in some cases pending approval connections can see non-public posts
if you choose this kind of permissions:
*Channel Permission Limits
Can view my channel stream and posts: only those you specifically allow
Can send me their channel stream and posts: ..same thing..*
and already you have some connections (already approved), or you will have and you will approve,
and you write a post (that is already not public and has a padlock 'cause of the channel permission limits), also "pending approval connections" can see the post.
