Where do I sign up?

I'm still new to this tax blogging world, but I've certainly read enough to know that I am not alone in thinking tax law is way too complicated.

Since recently reading that the Obama task force on tax simplification may not really get us anywhere, and also reading about how rarely Congress really listens to National Taxpayer Advocate Nina Olsen, I can't help but be discouraged.

I want to get involved in pushing Congress for tax simplification.

I realize I can't do much all by myself, and I've got two little rugrats to take care of, but I'd like to contribute what little time and (questionable) talent I can to making real change happen.

What's the best way to push for tax simplification? Is there an AICPA group, a group in the National Association of Tax Preparers, or some other group? Is there a "Tax Professionals for Simplification" organization?

What's the best place to start, and where do I sign up?
