when do you write konnichiwa this way: 今日は　and when do you write it this way?: こんいちは I've heard people tell me it was written one of these ways and others tell me otherwise, I've also seen it written in notebook entries both of these ways. Are these both correct? Are they both used in different situations or are you supposed to write it one way? If you're supposed to write it one way, then which way are you supposed to write it? Thanks.
