Hello Jan, Thank you for the welcome. Sorry I am just getting back to you, it's just I am usually off line on weekends. I too would like to see this list grow in the direction of discussion. I will do what I can on my end by telling others about this list and participating in any discussions that happen to come up in the future. in Christ, ben __________________________________________________ Do You Yahoo!?
