So I am surprised and very happy with the module "rules " . It is an extension of the "trigger" module and also a newer version of "workflow-ng" module .
It works on a simple policy of Event + condition = Action . And before someone thinks that its too geeky to use , this little picture would show how simple it is .
I was able to create a new page each time a user comments and also send an email thanking him for the comment in that particular page . It was also easy to substitute variables like user who commented ,user who recieved comment etc .
