As I commented before, I lost a whole lot of data in a disaster back in September. As if that wasn't good enough, mugwump got the boot from his company shortly afterwards and his hosting arrangements evaporated with it.
Well, I now host with Tantrix, and everything is back to normal. In fact, my reconstructed versions of things are better than the originals. And Grubstreet is back in action again. However, I hadn't done anything about bringing back the wikibot - and given that I'd agreed to give a talk about it at the forthcoming tech meet ("The One Where People Who Haven't Talked Before Talk"), I should have.
So, after a week of coding and learning, I can proudly present: the new, improved, shiner, more useful and more robust (hopefully) Wikibot. I'm happy enough with it to grant it a capitalised name, now, too. When the tech meet has passed (Thursday), I'll put up the source code for any and all to play with.
