Thank you very much ........

After reading your post I have no idea what you are asking for or what you want to do, so put some effort to explain your problem in detail, so anybody can understand it.

P.S. You can simply use spaces instead of dots in topics... And you can make the topic be a sentence or question, because now it's a group of words which says nothing to us.

Sorry, my English is poor ......
I was meant to create a business sector group manager

You need a universal, hybrid distance-vector protocol enabled by hybrid database.

As for the emergency. You need to call Dr Beat
