Understanding New Blog Notifications

Hi,

I've looked through the documentation and the forums and can't find any detailed descriptions of the how, why, where, and, when of EasyBlog's email new post notification settings. That has left me with a few questions about it.

1) Is there a way to set the system up so that my authors can send notifications only for the posts they select by simply clicking on the "Notify" button in the Blog Entries list?

2) It seems via testing that Send Notification Emails needs to be set to Yes for the Notify button to work. If a post is published and saved with Send Notification Emails set to No, will a notification be sent out if I reopen the post and set Send Notification Emails to Yes and save the item or would I have to click the Notify button after saving the post?

Any help would be appreciated.

Thanks,
Steve
