If you want links available off-line
We need to alter the filter

Try downloading "all sites in page (multiple Mirror)": 
 1. Put 2 desired URLs in Web Addresses for project
        <http://www.cert-la.com/calendar2/calendar.cgi>
        <http://www.cert-la.com/calendar/calendar.cgi>
  2. Option>>Scan Rules to include your domain's events
     -* 
    +www.cert-la.com/calendar2/calendar.cgi
    +www.cert-la.com/calendar/calendar.cgi 
    +www.cert-la.com/calendar/calendar.cgi?view=Event*
    +www.cert-la.com/calendar2/calendar.cgi?view=Event*
    -www.cert-la.com/calendar2/calendar.cgi?view=Search
    -www.cert-la.com/calendar/calendar.cgi?view=Search
    -www.cert-la.com/*/calendar.cgi?template=login.html
    -www.cert-la.com/calendar2/calendar.cgi?calendar=* 
    -www.cert-la.com/calendar/calendar.cgi?calendar=* 
    -www.cert-la.com/calendar2/calendar.cgi?year=*
    -www.cert-la.com/calendar/calendar.cgi?year=*
    -www.cert-la.com/calendar2/calendar.cgi?view=Month
    -www.cert-la.com/calendar/calendar.cgi?view=Month
    -www.cert-la.com/calendar2/calendar.cgi?style=*
    -www.cert-la.com/calendar/calendar.cgi?style=*

 3. Option>>Limits>>mirror depth = 1 internal ONLY 
      (External=0) 

This should download all calendar events
(I'm excluding non-events because they link to themselves) 
(In a link follower, that can lead to infinite loops) 
  
This will still lead to downloading a LOT of pages
 (I think 10 pages more than the # of events) 
 (I am erroring on the side of downloading less, here)
