Why would my name get changed to anonymous?

Question

I recently made a request to have a category modified by the Denmerk Project.  It was quickly and nicely done.  When I thanked the fixer, my comment was attributed to anonymous.  Why?

See:

Would someone from the Denmark Project please move Juhls to the correct category.
