I have just done an interesting exercise; transferring all my email addresses from my old PC to my new iMac. Now I am sure there is a very FAST way of doing this, but I decided to do it manually. The main reason was so that I could sort out and group the addresses and sift out some chaff along the way.
I decided to group them according to places I'd lived and family members. What is interesting is that out of the 542 entries only 20 of these are relatives. Out of those twenty, four are very distant relatives who we discovered as a result of my Dad's genealogical research.
Yes, I have a small family, but it appears I must come from a long line of Luddites. Come on guys, get with it. Buy a computer and get an email address!
