-When fighting another player if your damage is over 2873 it will not hurt them.
-USA-1 is full of jerks, always use USA-2 or the Horseman channel.
-Getting crashed is only a big deal if you make it a big deal.
-When in a chat room double click on your username on the right to edit your profile.
-There are no programs that are able to "Cross Hack" on Diablo. This means that when someone threatens to hack your character or offers to hack up your stats don't buy it because it's either a lie or they are just confused.
-There is no such thing as "town kill" in Diablo. There is a hack that allows players to cast spells in town, but when it's used only the person using the hack can see the spells and the spells do not effect other players other players (though the hack may cause the game to crash).
-If you try to join a game and it says that the latency is too high it may be a problem on your end. When all they games appear to have high latency get off Battle.net and log back on. When you try again at least some of the games will have lower latency.
-Ears do not do anything. You can sell them to the witch for a gold piece, but they are really just for bounty hunters to use to prove that they killed a particular person.
