Ayeesh! Glad youfound it! I'm wth Tygercub-- I always write the serial number on the CD. I also write it on a wee post-it note and stick the post-it note to the outside of the plastic case in the CD-wallet that they all live in (CD cases never make a transatlantic, I fear). I ALSO e-mail it to myself and keep a back-up of my e-mail archives: very useful, as most of my shareware serial codes are in e-mails.
