Rules are easy to do. You can do them one of these ways:
/help on text
on *:text:!rules:#yourchannel: {
msg $nick Rules are....
msg $nick More rules are....
}
Or:
on *:text:!rules:#yourchannel: {
dcc send $nick rules.txt
}
Change #yourchannel to the name of the channel you want this to work in. For multiple channels, use commas to separate them: #chan1,#chan2,#chan3
The first one will message the person with the rules. The second one will send the rules to the person as a text file if you have a file in your mIRC folder called rules.txt. Note that the second way allows you to send more text more easily, but the person requesting the rules needs to be able to download files and not everyone can do that. For the first one, you can just use a single /msg line, or two as shown, or more... whatever is needed. Just remember that too many /msg lines can cause you to be kicked off of the server due to "excess flood." Usually, that's somewhere around 5 lines per second.
