I've put a new version of the page in place. It is much less uncritical than what Gleb wrote.
... Er, but now that seems to be gone and I don't even see any record of my edits. Perhaps I needed to do something different on account of the page having been deleted. (I just visited the page with redirect=no or redirect=off or whatever it is, edited its contents to replace the magic #REDIRECT[[Delete]] or whatever it was, and saved -- was that wrong?)
Anyway, it looks as if Gleb has now recreated the page again, so it exists but is rather one-sidedly promotional.
[EDITED to add:] No, wait, I was seeing an old cached version. I think the wiki must be serving up pages with misleading cache-control headers or something. I think it's all OK.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
