See those dates next to my links? Date of the last update on those pages

I had an idea last weekend, (cutting grass is so inspirational!), and I thought about expanding the .plan idea to make it more like QuakeFinger. I’d like to be able to create a list of links to people with web .plan files with something to say. If I could get a shell account somewhere I could make it an auto-update page.
(Does nether.net let you run processes “nohup”?)
Mail me if you have any ideas or opinions about this.
