Hi, sorry been away for a few days.
ok goto this link
mirc.co.uk/cmds.html and scroll down the commands, and anyone will see the command
/who , the command works on the irc server i use, plus a few others, cant remember their names tho now
---taken from the command list---
/who {#channel} Shows the nicks of all people on the given channel.
This is of course just one way of doing what you want, i have a script that uses the /who command, and i have set it up for all the available isp's, and then all i do is select which isp you want from a drop down combo, and then it lists all nicks in a lister box.
