Your WordPress setup is for use as a content management system and publishing development tool. Plan your articles here. Structure your content appropriately (headline, paragraphs, quote blocks, image blocks, etc.) and consider ALL the different forms of media you might use. If you have your own video or audio, upload it to YouTube or to Soundcloud, and then reference your media from there: just copy-paste the URL into a new block and WordPress will take care of the embedding process.
If you can’t remember which site is yours here’s the list as we set things up before Easter. Contact Keith if you have any problems.
Note: if your home page says “Hello World” you haven’t published anything. Get to it!
