David, I've just read your topic. I found the idea is lovely and fascinating. I think it's very nice of you, to come up with the idea of a get-together event for forum members. Having said that, I think the chances to make it happen are next to none. Taking into account the geographical and socio-economic diversity of the audience of the forum, I doubt that many members would be able to afford to come to Moscow, or any other major Russian, or Ukrainian city, or Tbilisi to attend the party.
Unfortunately, it is logistically complicated and costly. I myself would love to attend and bring my beloved husband along, cause we love a good party. However, the reality kicks in and calls for more realistic Christmas plans. Still love your idea, though!
