We have had to switch to yet another commenting system, since Google has withdrawn its Google Friend Connect system. All previous comments are lost (thanks Google for not enabling us to export old comments).
The new commenting system, DISQUS, is powerful, and you can use it anonymous, or using your Facebook, Twitter, Google, Yahoo, OpenId log on.
However, thanks to the millions of spammers out there, all comments are moderated, so will not show up immediately. Sorry...
Let me know what you think about the new system... please..
