Welcome to the community. Your questions have already been answered in other threads.

The game has somewhat lost popularity, and less games are hosted now that the community is less widespread. While there are probably many people who have the game, it's safe to assume that they just don't know about us. If you advertise the community, we're probably going to get more hosted games.

Where you live doesn't matter, but instead what list server you connect to. The most popular and reliable one would be jazz.nimrod-online.com. All countries all over the world are supported on the server, so there is no need to edit anything.
