Play -> Mods -> Server Mods -> Configure "Show Me"

Despite this is server mod, there are client settings. These settings are the same server settings but on the client. Admin may set server settings as they want but a player may set their own settings of Show Me. Client settings will OVERRIDE server settings.

Undefined or Auto means that a player doesn't care about the settings on client side. So the mod will choose values or admin of the server may customize view of the client.

Some options may be forbidden by server admin.

Play -> Host Game -> Mods -> Configure "Show Me"

Each admin of a host or dedicated server may set mod settings to predefined values like Yes and No. Undefined or Auto means default value (it's different for different options). These values are transfered to the client and used if client hasn't defined their own settings for this mod. Client settings have MORE PRIORITY than server settings.

For example, let's look at language option. Admin may set "russian", because he started russian server and all their friends are russians. Most players on the server even don't know that there are client settings. But one admin's friend is chinese. They joined the server and see ShowMe hints in russian and they don't understand it. So they read this forum message, then they go to client settings, set mod language to chinese, and that's it! Now they see all hints in chinese, but all other players see it in russian.

Special option "Forbidden" means that the info will not be sent to the client from the server. So client will not be able to see it even if he wants to see and customize its view.
