I have to say, this method reads much better:

formatLinks = ()->
  msg = $("#weeee")
  for text in msg.text().match urlPattern
    url = if text.match(/^(http|https|ftp)/) then text else "http://#{text}"
    msg.html msg.text().replace(text, "<a href='#{url}'>#{text}</a>")

ABSOLUTELY. @daxter, that's a much better loop. Thanks!
