I will want to perform a clean install when SL is released in September. But, I would like to have my iPhoto library (events, faces, places, etc.), my itunes library (song ratings, play counts, etc.) and my Mail (messages, mailboxes, etc.) kept in tact. Is this possible? If so, how would I got about doing this. I know people have asked similar questions to this, but I have not been able to find a reliable answer for all these concerns of mine. Thank you to anyone who can help out!
