The first round of public submissions have been put up on the Treasury website, and it's good to see a couple of letters from concerned citizens detailing the abuse of tax-exempt status by the Church of Scientology. (Submissions by Graham Smithers, Hudson Carrad and Nick Renton mention Scientology)
The tax review is still going on and it will continue until December 2009. Submissions will still be accepted and considered throughout the review process. So if you haven't sent anything in, you still have time.
Privacy is a concern here because the submissions (and author details) are published on the treasury website. However, on the submissions page there is some info about maintaining privacy.
If you don't want your submission to be published, you can still send one in, just mark it as CONFIDENTIAL on the first page and at the top of your submission explain why you do not want your personal info released publicly (briefly explain Scientology's Fair Game policy).

Thanks for the update - it's something to follow up on for sure.
