Try this one. It'll send the contents of info.txt, one line every 5 seconds. The -m1 parameter tells the play command to only allow 1 request per user, even if they do a multi line flood of text. It's kind of redundant with the ignore command, but I like to be sure.

Code:
on *:TEXT:*:?:{
  .play -m1 $nick info.txt 5000
  close -m $nick
  .ignore -u600 $nick
}
