So, much editing of the database that is my phone was needed, I gathered my address book, Filofax, diary, pencil, paper, sat at the table in the garden, deleted, amended, changed names into lower case, added addresses, puzzled over names and emails of persons unknown to me. Where there is a field for company I have started adding the context in which I know the person, so a Mary Smith will have Great British Yarn Crawl2014 as her business.
It still took longer to type the details onto the small phone than to write them down, changed addresses are gone for ever on the phone, my address book and paper diaries are records of friends and families lives and house moves, but a phone scores high for portability. Haven't quite finished the task, there are entries requiring addresses but it is a start.
All this activity in the garden meant I spent enough time topping up my Vitamin D levels, much better than crunching ghastly calcium tablets daily.
