Forums Scripts & Popups getting channels

to get the channels on a server we type /list

so what is /listx ?

Not a clue. It might help if you would supply where you got that command from.

well by doing some google search i found out /listx is a ircx command but it doesnt seem to be documented in mirc :s

Probably because it is not really a command supported by mIRC, which is why it's not documented.
