Actually, this is perfectly fine. This material would work as an article, too, but there are no restrictions that say that articles must be posted on J2O and not as JCF topics. In fact, they can be as both; they are seperate establishments, and the JCF does not force articles to go onto J2O. On the same note, J2O does not force them onto JCF, but does recommend the JCF if an article is not suitable for articles but is for the JCF.
