And speaking of using SWUs, I was clearing out some old e-mails (ones that confirmed receipt of SWUs) and discovered that when using my SWUs last year, DL did not use the ones that expire soonest first. I had 6 that expire on 5/30/2011 and 4 that expire on 7/30/2011. I have 3 remaining and they all expire on 5/30/2011. Now thats another thing I have to watch with DL - make sure that they use the right SWUs. I'm going to contact them and see if they will extend the expiration date of my three remaining SWUs, but I have little hope of getting anything done.
