I know that many players are used to the concept of partner that comes from other games.
I intend to add this as a game feature, in order to prevent fraud, so until that happens try not to share the password to people you do not really know or trust.
I do not encourage password sharing especially since it can generate problems.
So before you give your password away, ask yourself if you really trust that person. If you have doubts then do not do it.
If your 'partner' will cause troubles, it is going to be you being held responsible.
If that partner would take your horses and coins, you must not complain to me.
So...BE CAREFUL
