Sorry if you feel that I am repeating myself with trifles not worth to bother the foundation list, but...
It seems that people have difficulties understanding the meaning of "distribute unchanged Wikimedia content, including appropriate attribution" at [[:foundation:Trademark Policy#Things You Can Do, a Summary]] (1).
So I suggest to add a new paragraph, called [[:foundation:Trademark Policy#Things You Cannot Do]], with:
* Anything that is not included in [[#Things You Can Do, a Summary]], including:
* Distribute any unfree WMF logo under a free license.
* Create adaptations or derivative works, which combine any unfree WMF logo with a share-alike-free license, because it violates the terms of that license : see "You may not offer or impose any terms on the Adaptation that restrict the terms of the Applicable License" in article 4-b of http://creativecommons.org/licenses/by-sa/3.0/legalcode .
Besides, I have the feeling, that "distribute unchanged Wikimedia content, including appropriate attribution" at [[:foundation:Trademark Policy#Things You Can Do, a Summary]] may require an explanation why this does not contradict "your website may not copy the exact look and feel of any Wikimedia website" at [[:foundation:Trademark Policy#Services Related to Wikimedia Projects]] (2). That apparent contradiction between "unchanged" and "not copy" would be best solved by adding the following at [[:foundation:Trademark Policy#Things You Can Do, a Summary]] or at a new paragraph called [[:foundation:Trademark Policy#Definitions]] :
*"Wikimedia content" : A) the central part of a collaborative wiki website page, including text, images and other media files, excluding the margin with the logo, the footer and any unfree header. B) any free file available from an internal download link on a File page.
Or we could replace the wording "Wikimedia content" by "Free contents contributed by or uploaded by Wikimedia users, including bots".
