Its not turning a Argo community into DMing community in any means.
/c sharecar : y use it man, when everyone can use ur car, and game's name is Grand Theft Auto, Ur car is mine car.
But in v2.0 maybe, there is a slight possibility of adding car alarms. Anyone atempting to pick the unattended car, alarm may go off.
But if u are car shareholder ( /c sharecar id), then alarm may not go off. Then maybe, we will find /c sharecar use.
Now tell me hows it related to DM server...
/c shareplace: can be implemented, but will completely ruin Hotel Business which will be one of prominent in v2.0
