I have for a long time been wondering why not a single soul has bothered to make even the shortest comment her. But when I took a look at the problem I found that you need a login identity befor you can post a comment. Google, Wordpress, Yahoo and a lot of othersd are available so if you already have for instance a google (gmail), or any of the other acceptable accounts, you can use that one as is.
I have been thinking of creating a google account with an public, open password so that comments would be open for everybody but I don't find that such a good idea since the same account could be used for login at so many other places, and anybody might change the password and make the account useless for everyone else.
