Hey
How about this?
alias annouce {
timer 0 1800 /msg $1-
}
menu nicklist {
Make Announcement:/annouce $chan $$?="Annoucemnet:"
}
Place it in remotes on mIRC. Right click the names list in the channel you want to announce in, Click on Make Announcement, Enter your message, then every 30 minutes it will repeat your announcement.
Then to stop it you need to type /timers - Find the message you want to stop (if its timer 1) then do /timer1 off
