One of the advantages for the Knowledge Democrats to have a group at Daily Kos is that group members can help collectively edit diaries. Some diaries may be queued for review by other members: the author can ask other group members for their input on how to improve a diary, etc.
Since all members have the power to publish queued diaries, it has led to some confusions, which I've attempted to clarify in the Daily Kos group wiki page:
You can easily submit diaries by other Daily Kos members. If you stumble upon an interesting diary which you think is a good fit to the group, you can submit it following the same simple steps as below.
However: do not publish queued diaries unless authorized to do so. Basically, you can publish all the diaries that you have queued yourself. Sometimes, other authors will queue diaries for a specific reason, for example: queued diaries can be collectively edited and review by other group members. Let them take the responsibility to schedule the diary for publication. On the other hand, it may happen that a member has queued a diary but does not have the rights to publish it. You may contact that member by private message and see with her/him when to schedule it for publication.
This is a simple rule. People who may want to take upon themselves to published a queued diary certainly mean well, so the rule had to be explicitly said in order to avoid confusion and misunderstanding.
