Like Bungle mention, read, read, read. There is a great search feature here, look through the threads listed here in this forum, most have asked similar questions and there are some great responses. Then keep an eye on the Leftovers and Player Updates forums. There is a lot of useful info there about players and situations. If you don't find something, you can always just post it(I suggest you search first
), someone will point you in the right direct on where to find it or they can directly answer it themselves.
