I can find the oopses (and it's really good with the whole search-and-clump-together-by-version thing), but then when some oops like this is found, it's hard to see where your kerneloops scripts found the oops from, so the context of the oops is all gone. Is there something obvious that I'm missing? I'd really like to see the whole posting that the oops came from. Do you save the originals or even just message ID's from the ones you pick from emails?
