INTERFACE FOR MODULES

Mostly via blocks:

Replys and saving comments from "New comment block" via "Comments" modules CommentMgr?

Also "native" interface CommentContainer? something like this: 

if(this->conf['commentsEnabled']) {
	// create CommentContainer for uri
	$commentcont = new CommentContainer('simpleblog/post/' . $id);

	// if just want to display count on "summary page"
	$output->countOfComments = $commentcont->getCount();
	
	// or grab comments and format/manipulate them self
	$aComments = $commentcont->getAll();
	// get all in tree childs like this: $comment->children[]
	$commtTree = $commentcont->getTree();
}
