Have a technical question you can't find the answer to in FAQ's? Ask it here. Game problem questions that do NOT pertain to things like training advice, what would my horse do well in, how much is it worth.
Typically, you should send a support ticket into Orbis Games if you want a name/ranch change, although, as Alias said, Ops won't change your name unless you have a valid reason for it [Example: Sale of ranch, ranch gains new ownership etc] - Just because you don't like it anymore doesn't count as a valid reason usually.
Note: Be careful when choosing names, the one you pick, you have to live with. =]
