When a user have a project on pages (e.g. Putting the Trading category on items/blocks that can be traded), they can post a message on the thread. Other users can see it and also help edit, thus they have more edits, and more (user) wiki activity.

No it's not a checklist, but maybe you're right; it might be unnecessary in this point.
