Here was a small tip for which I browsed a lot but could not find help. So, finally when i discovered this tiny titbit, felt like sharing.
If you want to change the email address to which comments on your blog are to be notified ( assuming you are using blogspot), then, go to dashboard, settings, comments tab and towards the end you have a place to tell which email id should receive your comments. Type it in there or change it there and you are done.
This may be trivial but of some help :)
