Everything is possible, but if knew how to do that, it would be on my server too. Although this sounds good for players. I have no clue how to get it to display the player scores and kits. Etc... But to enable a greeting like the one you describe. Go to:http://www.pbbans.com/account/server.php
Click "Modify" and under "Join Greeting" Type:Hello $CURRENT_NICK, (And your server message) If you ever find out what the codes to display such info -- enter it after "$CURRENT_NICK,".
Please post the codes here if you know what they are...
Anyway hope it helps. :)
