This is the first module i have tryed to make and it is very simple.
It simply includes a html page that has the pjirc applet setup on it in a basic xoops module.
Until i learn more there is no admin section so you need to config it just like you would configure pjirc.
So just edit the file irc.html for server, channel, nick etc. and upload the xpjirc directory to your sites modules directory and install it like any other module.
PJIRC is developped by Plouf - plouf@pjirc.com - http://www.pjirc.com/
i have nothing to do with pjirc in any way i just wrote this module.
