I got some mail in which friends pointed out that leaving a comment wasn't possible. I do love comments so it's a pity that not everyone can comment on my posts. So i have changed some set ups. Now anonymus comments are also possible: for those who haven't a blogger account. I would appreciate it if you leave your name in the comment though. :-) And instead of placing the comments under the post i've changed it into a pop-up. I hope it will work out now for everyone. Please, let me know if you can't comment on my blog by sending me a mail.
