chats

Ok, I know how to chat in the guild chat, in the party chat, and I know how to say something where what you say appears over your head. But how do you talk to other players using just "general" chat or "trade" chat?

i was recently in the chat just simply talking and they totally started flaming @ me for no reason and al i ddi was ask if anyone wanted to be a map makler for my clan, i was banned for simply talking to people they were harrasing me and if something isnt done i will personaly talkt o the maker...
