Just thought if you're about to fly someplace from moscow it would be handy to have a place on the net to post
i)which airport youre departing from,
ii)at what time you're planning to arrive to the airport, and
iii)which tube station you're starting from
so that people could carpool and spare themselves expensive taxi service.
this is a sample of how it was done in the context of commuting to work: http://www.metro.net/riding_metro/commute_services/carpool_work.htm
