I was hoping to see a number of the more organised thinkers here sending comments about .xxx but I haven't seen any. I posted mine and I think that any comment that's well thought out, avoids anger and is written in a professional manner (spell checking) could only help the cause. Of course comments written in an unprofessional manner may not help.
If you want to help send comments to
