there's a full range of settings in the Display settings tab

Thanks; I hadn't spotted that. Unfortunately all the boxes are ticked and the navigation strip still isn't showing up for me; my guess is that that's because my S2 code is failing to call whatever method optionally inserts the navigation strip into the generated HTML. I should probably just go and find the docs and work out what I should have called and where. (Which of course will be easier now you've told me the proper name for it.)

Custom posting software, hm. What are you doing for backup / archiving?

Hmmm. Perhaps I should have said "horrible hacky script" instead of "custom software", to give you a better idea of its general level of organisation :-) I don't have a full-on client by any means; all I've got is one script which lets me write posts in a markup language I made up off the top of my head, and then formats them into HTML for LJ, into plain text for posting to a private journals newsgroup, and into colour-enhanced plain text for posting to Monochrome BBS (where I've maintained an online diary since before LJ and blogging were famous :-).

Archiving of my LJ is something to which I have so far not taken a particularly joined-up approach. The posts I make are archived in the form I post them on Monochrome, because I happened to already have the technology to do that. Comments on my posts are archived either in my email archive (which is why I like self-comment notifications) or in a big directory of HTML files I created one day by spidering my entire LJ (the idea being that the latter covers all the comments from before I started keeping those emails).

It would probably be a good idea to look into sensible content exporters, but it's a long way down my to-do list at the moment...

Aha, found it. It's called Page::print_control_strip(), as it turns out.

Yeah, I was just about to say that the names in the code don't always match the names in the docs. Dreamwidth is turning into one of those Open Source projects that has issues with documenting things properly, either for users or for developers. Anyway, you found it faster than I had time to explain this to you, so.

I still found the name by searching for "navigation strip" on the S2 wiki; the names may be different but they show up close together in the code, so it's easy enough to follow the clues and end up in the right place :-)
