each post on own url

I’d like to be able to do this too!

If you mean like this:
https://www.billhayes.us/wordpress/archives
get the narchives hack.

This hack shows everything, but perhaps too much to the liking of juliecookies. I also looked for a way to let people first choose a category and then displaying that same page with a title “categorytitle” and a list of all the posts with permalinks which would result, again, in that same page (with list + pagetitle) but then displaying only the content of that one post.
This would look nice when you have a category within your blog that says “Poems”, because a poem is nicer to read when it’s a single poem isolated in a page, instead of fifty poems on one page.

That is a function of how you have permalinks set up in WP, not done within narchives.

Where do I find the narchives hack? It might be closer to what I’m looking for than what I have right now ??
You said it, Moxie, “This would look nice when you have a category within your blog that says “Poems”, because a poem is nicer to read when it’s a single poem isolated in a page, instead of fifty poems on one page.” This is exactly what I’m hoping to accomplish.

For hack and other documentation don’t hesitate to read a little bit on the Wiki!
In the top horizontal menu click DOCS, then take a look at the right menu ??
