Sparky, alas, at this point you have no choice. The period to submit proposals will close, and we need to wait until Summer to comment on proposals already made.

Illusion of choice? When voting for a politician, I don't demand that my guy win ... but I do insist that I have my vote. In a like manner, I see little point in being critical of the code, while not at least making your opinion known in the circles where it can have some effect.

You have at least two basic places where your opinion matters. One is by making a proposal. The other is at the local level, where you can affect the adoption and enforcement of codes.

I'll give one example, from the last cycle, to illustrate that the NEC is not always a 'done deal:'
A proposal was made for the NEC to allow illuminated closet rods. The committee said "no." Comments were made ... the committee reversed itself ... and the 2008 now recognises the use of this new product.
