- Description: Two letters from the first tag, then the date. A library catalogue for a blog nobody asked to be catalogued.

Each card carries a filing code, like `#GU260924`. The letters come from the post's first tag (*Guide* becomes `GU`), and the numbers are the publish date: year, month, day.

Notes on the Scatter wall use their kind instead, with the time added, so `#TH260926·1745` is a thought from a quarter to six on 26 September.

There's nothing to set up. Tag your posts and the codes appear.
