Or you can make it go into your Remotes tab, by changing

/F1

to

alias F1

What would be better is to perhaps change it into an on CONNECT script?
Example:

on *:CONNECT:{
  if ($network == PeerCommons) { msg NickServ identify <password> }
  if ($network == FanNet) { msg NickServ identify <password> }
  if ($network == StrikeX-Network) { msg NickServ identify <password> }
}

You can also shorten the script by changing

msg Nickserv

to

ns

I also would suggest is to add an on LOAD script to set a default nick and password for each specified server by using variables, and an input-dialog at start.

Not everyone uses the same server as you, too.
