We'll publish a link to the data dump and a list of posts that will need attention as soon as we have them ready.

I don't know how much effort is worth investing in that, but make sure the list is searchable at least by author and tags. It doesn't need to be anything fancy, even something as simple as a CSV would work too, but don't provide just a flat list of links.

• I'm willing to update my answers but I need the author field to quickly find all my posts that contain a documentation link and need attention
• Then I assume most people who want to help would want to focus on their area of expertise first, and that's why the tags are needed as well
