Questions :
-there is only public server's? like if you get 1k on server #1 on any server you will have 1k or the database for all server its not same?
-if they are Private server's [created by community] the owner can add mods/new texture and get options like map editor/Scripting etc.
Suggestions :
if you are the chief of police, you can create new units/departments like sert/swat/marshals if they not exist,and you can change everything in the police like rangs etc
