[K12OSN] K12 V4 app question

[Brandon Kovach]

I am new to the K12 thing.  I have a setup going now of 8 computers and 
a server.  I want to remove the games from the student's group desktop.  
I have the student group created.  I know that essentially, I need to 
Chgroup the application, but I am not proficient enough with the command 
to do so with any certainty.  Is there a GUI tool somewhere that will 
help me allow/disallow applications to a group?
