I made a script to know who is connected to the admin, and also to set nicknames to each admin. So you can use this command when you connect to the admin:
/nick YourNick
Also if you write /admins, you'll see a list of the admins connected. You can't tell who they are unless they set a nick.
Everytime an admin use the /say command, their nick will appear before what they write. There's also a /saya command, which will echo the message along with the nick but only to the console. This was more usefull when not everything was echoed automatically to the console.
The script is attached, hope it helps you.
