I deleted the post which had attached a modified version of a PHK wps, as it (said WPS) is copyright All Rights Reserved (this means no shared modifications).
This may not be the ideal intended by PHK, but it is the law. He has no license expressly mentioned in his themes.
This is a perfect example of why all WPS authors need to be explicit about the license they release their works under.
Feel free to discuss how to fix any specific WPS, but no more sharing of WPS files you do not have rights to.
