Is there a nice little plugin here that could at least tell us which non-existent pages we have internal links to? How will we know when the transfer of articles from the old wiki is complete?
There's a "wanted pages" button hidden under the "site tools" button at the bottom of each page, which is what I was looking for, though it's far from being a perfect tool for the purpose.
Can that list be linked to directly?
I asked on the wikidot community pages, and apparently there isn't a way of doing that yet. But perhaps someone will write an appropriate module for it - the moderators there moved it to the "New features and ideas" subforum.
