When newbies come in to the game, they don't know what the fuck to do and @newbie goes (and can only go) so far in terms of IC information.
I was thinking it would be a decent idea to have an immigration package/pamphlet given to newbies when they go through chargen so they get an immediate taste of what exists in Withmore in terms of housing, jobs and attractions as well as a quick rundown of the Law and the justice system.
It could either be an ingame item, or a PDF that could be linked from inside the game (in this way, it could even be used as marketing material to get new players interested).
I'm sure all active players would be able and willing to contribute to and help create such a document and would require next to no GM involvement short of looking over the content to ensure it meets the spirit of the game and divulges only the necessary IC information, and to plonk it somewhere in chargen.
Just an idea to help motivate new players to stick around.
