Due to a multiplicity of crises such as replacing our car due to a blown head gasket, disposing of the wreck, trouble with a gang of local children etc etc, Jackie and I are ages behind with things right now. I am trying to catch up but notice that today I have 350 unread GML messages! I will try and reply to anything that has not been replied to by anyone else if I have something useful to add. I hope that is helpful. -- Julian [EMAIL PROTECTED] National Gerbil Society http://www.gerbils.co.uk/
