On a more practical note.
At this time it is extremely difficult to ship parcels and documents to Russia due to some tit-for-tat customs regulations that went into effect at the end of December. As some of you more experienced people already know, whenever the US tightens some customs or immigration rules on goods, services or visas from Russia, the Russians do a counter measure. This is coupled with a recent change in contractors who do the actual FedEx pickup from Russian Customs houses and delivery. The result is an airport coustoms house chock full of undelivered FedEx shipments dating back to the first of the month.
If you are like me and have reason to routinely ship items to Russia, beware of FedEx. I am actively looking for an alternative method, if I find another more reliable possibility, I'll post an update.
