This is so you'll avoid sprinkling garbage characters through your mail.
以免在你的邮件中到处散布垃圾字符
In web forums,do not abuse “Smiley”and“HTML”features.A smiley or two is usually ok,but colored fancy text tends to make people think you are lame.Seriously overusing smileys and color and fonts will make you come off like a giggly teenage girl,which is not generally a good idea unless you are more interested in sex than answers.
在论坛，勿乱用表情符号和HTML功能,一两个表情符号通常没有问题，但花哨的彩色文本倾向于使人认为你是个无能之辈，过于滥用表情符号，色彩，字体会使你看起来像个傻笑的小姑娘，这通常不是个好主意，除非你只对性而不是有用的回复更有兴趣。
