[I will try to write in basic English so this translates well with automated language translation machines. However, I know that most Germans speak English. :) I am sorry I do not speak German.]
I have translated the YAMLEE to English. It is not perfect, but I would like to offer it to others. I would also like to help transition YAMLEE to the current version of YAML. I am new to XHTML/CSS, so, I can not offer much quality in my help --but helping on this project will help me learn YAML, Expression Engine and XHTML/CSS.
You can see an example of the English version of YAMLEE here: http://www.acstrat.com. I have yet to customize the layout --as I am learning how to do this.
I really thing that the YAMLEE is a very useful implementation of YAML.
P.S. I have purchased the commercial YAML --so I am permitted to remove the YAML brand on my sites. I am not certain whether this permits me to remove YAMLEE references also. Most of my commercial clients would prefer to not have YAMLEE references on their sites. So, this is why you do not see YAML references on my test site.
