Looks like you all had good fun :P, I hate to say it but this probably won't help get more players, it may get back a few players who left, but it won't attract new players. Things like the Christmas event will also bring players who left back, till they once again get bored.
I honestly think to get more people playing there needs to lots of new content(for people who left of boredom) and possibly features from current existing MMOs brought to the game(to branch out to new people who haven't tried Mir yet). The server is very well developed and looked after by the Team, but it will never reach the usercount it did when it launched, which is a shame cause 200 players may seem like a lot on Mir, but in reality it's a very small amount.
