And one tag will belong to many items. This implies to me that you'll quite possibly need an intermediary table to overcome the many-to-many obstacle. Something like: Table: Items Columns: Item_ID, Item_Title, Content

I can tag a post using the YAML front matter, but how do I generate pages for each tag that can will list all posts for a tag?
