blog posts comments delete and edit

What does the setting in membership actions "blog posts comments delete and edit" do?  Does that grant complete control over all blogs by any member to the member that has the membership level that action is enabled in, or just the comments left on the user's blog?

I still don't understand a lot of these bits and pieces to this app.

Yes,  member with "blog posts comments delete and edit" action allowed can delete and edit any comment in Blogs module.

That is not what I want then.  Members are asking to be able to delete a comment left on their blog posts; which they should be able to do since it is their blog and their blog post.  Is this built into Dolphin 7.1?

 No there is no such functionality by default, however it is possible by implementing small modification by changing the following code:

    function isRemoveAllowedAll()
    {
        $oMain = $this->getMain();
        $aBlogPost = $oMain->_oDb->getPostInfo($this->getId(), 0, true);
        if ($oMain->isAllowedCreatorCommentsDeleteAndEdit($aBlogPost))
            return true;
        return parent::isRemoveAllowedAll();
    }

to:

    function isRemoveAllowedAll()
    {
        $oMain = $this->getMain();
        $aBlogPost = $oMain->_oDb->getPostInfo($this->getId(), 0, true);
        if (getLoggedId() == $aBlogPost['OwnerID'] || $oMain->isAllowedCreatorCommentsDeleteAndEdit($aBlogPost))
            return true;
        return parent::isRemoveAllowedAll();
    }

in modules/boonex/blogs/classes/BxBlogsCmts.php file.

Thank you Alex, I appreciate the help.  This will allow a member to police their own posts.
