Open the friends list, there is a "sentence of the day" in the upper left corner, enter what you want to say in it, and then click the floppy disk-like button on the right to save it. So that others can see your signature. Some icons are specific symbols, some are downloaded from 178, and they are a set, so I won't put them here. You'd better find the website yourself. After all, I tell you 178 is more fun. It doesn't matter if you don't score. I hope I can help you. Have fun.
