People Database?

Last weekend, I went to Centre Parcs in Sherwood Forest. It was a chilled out stag/hen night for some friends of mine who are about to get married. I knew almost no-one there but everyone was really friendly and I had a great time.

I found out quite a bit about the people I met and I’ll be a little embarrased if I can’t remember who is who when I go to the wedding in a few weeks. It occurred to me I should write some notes, then I thought maybe I should have a little paper “people” diary. I dismissed the idea of setting up a database as overkill but does anyone use any technological aid for this sort of thing?
