I have written about hypermiling before, but it was through Autoblog Green that i came to learn about Clean MPG: http://www.cleanmpg.com/cmps_index.php?page=hypermiling a nice site that I signed up on at once. I am no expert - and I am happy to admit this whenever asked. As a learner, I do think that many who visit my blog would find this a useful site. DO try and use some of the techniques that they talk about to save fuel and post back to let me know how you find this. And, of course, do sign up.
Thanks and happy saving through hypermiling!
