What you describe is exactly what I would like to achieve with the next
version of the program but one which uses 2 databases, one provided
by an organisation called CAMRA - www.camra.org.uk and my own to record
any visits to pubs and the beers I drink there.

But that's some way away as I my programming ability needs to improve
considerably before I can do such things! When you get to my age, these
things don't come easily. Certainly they don't for me.

Perhaps I should leave things as they are on this program and
concentrate on the new one!
