quick rules question

[walterberk]

Looking for a response ASAP.
In a home NL hold em game, what are the raising rules? We always say minimum first raise must be at leat the big blind, but what about a re-raise? Does it have to be at least the size of the previous raise? Does it have to be at least the size of what has already been bet for the round? A quick response would be much appreciated.
