messageAllExcept(%exceptantClient,%type,%message);
// Variables:
// %exceptantClient is the client you are NOT messaging
// %type should be two single quotes (null) unless you are using MsgAdminForce, MsgClientJoin, etc.
// ^ If you don't know if you need to use them, don't use them. You will know if you need to use them, really.
// %message is simply the message you are sending
// Examples:
// messageAllExcept(findClientByName("Truce"),'',"\c6Truce is a \c0cigarette\c6.");
// ^ Basically this would be talking behind my back ;P
// messageAllExcept(findClientByName("Kalphiter"),'MsgClientJoin',"\c1Kalphiter2 has connected.","Kalphiter2",999999,1337,0,0,1,1);
// ^ Adds "Kalphiter2" to everyones NPL_List but yours. Displays message for realism and sets their BLID to 1337.
I don't think this is used very much anymore, if at all.
My script searcher couldn't find it in any of the add-ons I have.
