Several problems with comments

Hi,

I have spot some problems with comments in articles. I'm using jomsocial integration.

1 - regular members can edit other members comments.
2 - owner of the comment can't delete his comment
3 - Comments deleted by admin don't remove the entry of that comment in jomsocial wall.
4 - Comments edited, don't change the text on the wall entry of that comment. Bacause this probably is not possible to do, when some one edit a comment and post it, the previest wall entry should be deleted and a new one created.
5 - If guest comments is enabled, and the guest don't register, just add is name to the form, the comment is posted with the guest name but with the avatar of the member that is viewing the comment. This means that all members that see that comment will see their avatar on the comment, and all of them can edit the comment.

Thanks
