You'll need to do most of this as root.

You can use the symbolic form literally. I think it's easier to 
understand.  Let the computer do the binary/octal math.
  g+rwx means add the read, write, and execute bits for the group.

> chmod +t ( What number of +t ) /home/edward

Same here, you can type it that way and it means add the "sticky" bit.

Don't get carried away with wildcards on this one.  .* will also match 
.. which is your parent directory.
