I recently upgraded to Lightroom 2 (2.4 in fact). I haven't ever used it much but owing to the increasing number of photographs on my hard drive and the fact I can never find what I'm looking for, I decided I had better start cataloguing them all!

However, I have broken links. How do I find all the photos with broken links so I can update them or delete them from the library as appropriate? (Some of the photos were downloaded from CDs attached to mags - and I don't want them in the library.)
