Astonishingly, the third party Haloscan comment system is blocking comment postings from our normal IP address and from our ISP's proxy servers with the message
"Sorry, Tor users are not allowed to post due to abuse"
However, we have successfully posted two comments, via two different Tor exit nodes !
