These work in progress posts are visible to everyone, and members with a trust level of two or higher can reply to topics. Members added to the Contributors group can create new topics, as can members with a trust level of 3 or staff-level permission.
I’m hoping that people might find it useful to have a communal space tucked away space for their drafts.
The idea is that most threads in Drafts should be wikiposts. That way, we can collectively develop content over time, make suggestions and edits to each others’ work, then later move it to the appropriate public categories (perhaps some research topics will split off into more specific threads, for example).
