Saying "Hello" to family members?


On lang-8 I read a message from a Japanese speaker who said that 「今日は」isn't
used among family/friends, but mainly for strangers.

To this end I need ask, what is a common way to say "Hello" to family/friends,
or at least the Japanese equivalent if they have a different custom in this
regard.




In the site below a native Japanese student admits he doesn't greet his family
or friends.

But that is not considered good manners. As an adult you are supposed to greet
promptly and correctly.  
A child may get away with it, but not an adult.

こんにちは is the proper way to greet people.  
I don't think there is a good substitute for it.  
Any possible substitute will be probably a slang or dialect, which by
definition is used by a small group of people and may not be appropriate for
certain situations.

If it is a close friend you could maybe say something like "元気?"  
I had a co-worker who used to greet people with "おっす".
