A group blog

[kmk]

I would like to suggest add ability to hide "Entry posted by x" (red), because the nature of the "A group blog by x" is show the entry as posted by the group that already named (orange), that is I want too, show the entry as posted by the group and not by some member. 

Anyone can tell me how can I hide remove the entry author?

The other area where I want to remove the entry author from the Our Pick widget.
