ok youadd this code to script remotes, it allows you to have several nicks in your pm or whisper box, tho no matter how many you have in it others cant see the message , you talk to everone seperatly in the same window.

Add this to nick list popups. Chasnge the  $+ $nick.decode($1)  to what ever your server uses to decode nicks

-
Whisper: { whisperto $$1 }
-

Open Mirc Options go to Mouse & where it says /query $$1 replace it with this (note if you dont text wont show up in the query box.)

/whispers $$1

final code add this to remotes of your script.
