USA Glider Experimental Airworthiness Certificate

Well, now I've done it. I've changed the tail number of my glider, and
I'm in the process of getting a new experimental airworthiness
certificate. My glider currently is certified as: "Experimental:
Exhibition and Air Racing." The DAR (FAA Designated Airworthiness
Representative) says that I am required to submit a "Program Letter" to
the FAA annually detailing where I will the glider will be based, when
and where I will be racing, and every other place I intend to fly it.
Does everybody need to do this?!

To those of you who have an Experimental Certificate, do you have it
liscensed under Exhibition and Air Racing or something else? Do you
need to submit an annual Program Letter to the FAA? Any advice you
have will be a great help!

Thanks, and safe soaring!
