Whilst working with (and updating) an article I have stumbled into a potential issue with licensing. The article code clearly states the source of the code for several of the methods and if you go to that source then there's a licence statement that may possibly give rise to some issues.
I didn't want to identify the article directly, in the public domain, but I could not work out how to report it privately (e.g. private message), so here it is. Let me know how to proceeed, private message or reply to this thread or an article comment.
