Guys, you're bad :) OK, I agree, my post about the phone service of Vinogradov Institute was off-topic and could be closed. But you should have up-, not down-voted it. The information was interesting and useful. Besides, you were so fast that deleted it before I found time to see your comments outside my email and have a chance to answer. Anyway, like this I at least don't see how much rep I lost on it :D
