I've had some trouble with Boost Log that I can't overcome. That coupled with the fact that it actually is not part of the core of Boost, but have to be built separately have made me change my mind about the logging I will use with the Shadow World server.
Every time I start (over) with a MUD server, one of the first bits I do is the logging. Not only because it's easy, but because it's very good to have at an early stage. For the Shadow World server it's no different.
