The article is incorrect. An amendment doesn't require Congress at all, it can be proposed by "Application of the Legislatures of two thirds of the several States" and ratification by 3/4 of state legislatures.
Get hold of your state houses, get this thing proposed. One more point, whichever version gets proposed needs to not have a time limit on ratification, so that future generations can take up the cause as debt and deficits get worse.
