Thread:User talk:Armondikov/Licensing of portal icons

It would be really useful if an SVG version of File:ICON homeopathy.png was available under CC-BY-SA - this way there would be a template from which new portal icons could be created using e.g. Inkscape. For example, I recently created File:Icon nuclear.svg from File:Icon creation.svg, but after noticing the icons are not under a free license I'm not sure whether it was allowed.
