I figured that because the new markup requires brackets around every link anyway, the page titles might as well look a bit nicer, but I kept the old names so as not to break any links I haven't edited yet
The page somehow got deleted, and I was able to restore it, but I can't edit it now--it just throws up an error message upon saving
Other pages that link to AlicornSystems seem to be affected by this as well, Blathr threw an error message when I tried to save an edit
This one I figured out. It was an unrelated bug...seems Moin2 doesn't like it if you copypaste certain character encodings. Not a big deal, I just won't do that, then!
Some of the old CategoryWhatever style tags are still listed on the tags page, presumably because they're still associated with deleted pages
Most of those deleted pages were redirects on the Moin1.9 site that I mass-deleted because the old redirect pages don't work on Moin2 anyway
