Good point. I forgot about the line length. That could be split to about 50 or so nicks per line and then create a new line, of course.
Timers would work. I was thinking along the same lines, but using /play. Either way, 1 second delay will make a message get sent to the last nick in a 300 person channel 5 minutes after it was sent.
Personally, I'd just message the channel if it's important to message everyone. That, or change the topic to whatever is needed.
