Google announced today that all AdWords advertisers could use the AdWords automated rules. Last December Google AdWords allowed some of it's advertisers to use and test the AdWords automated rules, which automated changes to the AdWords account based on specific criteria.
It is very advantageous for AdWords advertisers who change their accounts a lot like stopping and starting their ads based on certain times, adjust bids and other such tasks.
To get started, Google has a lot of help at AdWords Help Center, where you could learn how to use the feature. If you are a user of the feature you also can provide feedback to compliment or point out ways to improve the program by filling up this survey.
