Hi, thank you very much to you all for the help. Your suggestions have been very useful, i'll try to see what's the best we can do with our current setup, and knowledge, and see how and when we can have a better setup. Thank you all again! Riccardo PS: How's the situation going in north and eastern europe? The news reported here in Italy are drammatic.. If any of the collegue may need help to keep the services up, and we can handle it, wee'll be glad to help!
