OK, this might seem like a silly question--but I've been wondering about this for a long time! I see several posters here who use hyphens like this - (space, hyphen, space). But I've always been taught that it's like this--(double hyphen, no space). Sorry this seems sooo random, but I've always wondered, which is the correct form?

In several newspapers, it used to be what I used. But then I was reading the paper the other day, and it was like this - . Have the rules changed?

This is just for future reference...hopefully I can learn now so that I won't make mistakes in the future!!

Again, so sorry for it being so off-topic!!!
