Weekly Sunday School materials are posted in an archive on the Christian Education page. The materials are posted in both PDF and WORD format. In addition, the availability of new Sunday School materials is announced in a post. It doesn’t matter whether you create the post first, or add the materials to the archive first: the materials will be available to whichever you do second. (Although, I don’t include the WORD version in the post announcement.)
To provide variety in post authors, I post the announcement as the Sunday School account, and I use a “Sunday School” image as the featured image. All blog posts get automatically cross-posted to the parish’s Facebook page, and apparently posts get better visibility if they have a featured image. (Because of Facebook’s recent restrictions, you can’t automatically cross-post to individual profiles, so if you want posts to be cross-posted to Isaac’s account, you have to do it manually. The simplest way to do this is to be logged in as Isaac, go to the blog, and click on the “Facebook” sharing button for the appropriate entry.)
