Can anyone please give me some advice in organizing my address book.

Frankly its in a mess.

Trying to get all the contacts in to 4 individual groups.Each one separate
from the other.

Try as I will I am unable to understand how filing system works.
I only need an address once, not scattered all over the place.
Any tips please?
I did wonder, should I switch to Outlook, is that any better.

Mike
