Hancock, thanks for that. Here is that link again with the gubbins to activate it: Hypertext Poetry Workshop. It looks interesting.
On the question of comments, I have added Squawkbox's free user comments system to the template here. Readers can now post their responses. To see how it works in practice, I added some comments to the this: the dog lists.
Note: they display I.P. address etc. alongside the messages.
There are issues with the links and archiving not working reliably here. I have opened a case with Blogger about them.
