I am not certified, but, I could help you with change management, request fulfillment, service level management concepts, we developed a tool and got it certified from a third party as being ITIL compliant.
Me too, not certified, but I joined this organization in January this year.
And ITIL is a mandatory internal training program in ours which I completed recently.
It is good. There are a lot of things which we do but do not know what they are called or exact process. ITIL describes them well.
