Okay, so you asked about signatures...if you go under your setting, near where your avatar is, you can edit it. But if you want to put a picture in your sig, you have to draw one, buy one or find one...also it has to be under 250 pixels in height. Also, when you are trading with someone and go to their town, do not explore or run around, becuase remember you are a strange to them and they don't know if you will take something or not... You should also make a post in the Re-tail sub and ask for bush starts.
