I can tell you based on experience, most users will not even read these types of messages. However to add this info you would do something like the following. (I did not test)

Please see the FAQs - http://www.kixtart.org/forums/ubbthreads.php?ubb=postlist&Board=5&page=1, specifically find "how to use a UDF."

 Code:
$x=14
$y=45

If InGroup ("desktop") or InGroup ("temp_users")
  mapdrive("H:","\\server\%username%$$",$x,$y)
EndIf

$x=$x+1  ;move down one line
If InGroup ("staff") or InGroup ("tusers")
  mapdrive("Z:","\\server\share1",$x,$y)
EndIf

$x=$x+1  ;move down one line
If InGroup ("HR")
  mapdrive("p:","\\server\share",$x,$y)
EndIf



The code below is a UDF (User defined function) Copy this code to the bottom of your script so the code above will work.
 Code:
function mapdrive($letter,$share, optional $locationX,$locationY)
  use $letter $share
  if @error=0
    if $locationX
      at($locationX, $locationY) + "Drive " + $letter + " Mapped"
    endif
  endif
endfunction
