The tournament and a question of ethics - newbie question

[tbontob]

Let's define some terms first insofar as they may apply to the tournament:

1) Illegal - an action or non-action that contravenes the rules of the game.
2) Unethical - an action or non-action which is not illegal (i.e. there is no specific rule against it), but it is something which is generally frowned upon.

I went to the game site and found little to guide a players conduct.

For example: Communication...what is permitted?
a) Only Messages which are allowed through the game interface.
b) Any kind including e-mail, telephone, face to face etc.

a) above would seem to be the fairest but there is the question of discovering the infraction (very difficult), and enforcement.

So b) would seem to be the applicable standard to be applied...that is any and all kind of communication is permitted.

I have a whole bunch of additional questions, but want to take this step by step...in case I take a wrong turning along the way
