I’ve been thinking about this question for a few days now and this is how I’m going to be doing this moving forward.
All my /now pages will actually be blog posts under the “now” category. My actual /now page queries for and displays the latest post in the “now” category.
This way I would have an on-going record of previous /now pages.
If I ever get around to doing a Toolbox/My Tools page like @Lioncourt or @Ronguest, I’d probably use this method again.
