Hi Giovanni, Thank you for the update. I am sorry to hear that Sindice is going into a frozen state, and that circumstances are making that happen, but of course pleased that you are able to keep it going at all. I send you and your team my personal thanks for the service you have provided over the last 5 or so years, and wish you all well. Very best Hugh.
