NOT silly at all I was really interested in hearing peoples replies to you, so I could learn about this too. Although, I think Geoff or someone else explained this to me long ago, and I've just forgot? My mind is going when the years do I think!

By the way Lucy, I love having another woman posting in here!!! So few women have gotten really active in here. Maybe I'm just a strange one? We'll have to inspire Pauline to come back and post more as well
