Rules & interaction with other players

Where can I read the game rules?

I believe that one of the players is breaking the rules of the game. What can I do?

How do I report in-game messages?

There is a player calling me names. Can you please punish him?

Can I play more than one account on the same world?

Can a friend in my alliance use my account while I'm offline?

If I report a player, will he know who reported him?

Can I know what ban you gave to the player I reported?

The account of my friend/alliance member was banned. Can you tell me the reason for the ban?

Can I play from my friend's computer?

I cannot attack someone. The game says I have a shared connection with him, but I don't.

I have a shared connection with another player. Can we both build the World Wonders?

I want to offer my help to other players and protect them, but they should give me gold for it. Is that allowed?
