Designate individual group members to move content. Remember, just like in your group sandbox, when multiple users edit the same page at once it can cause edit conflicts.

Here's how to move drafted content:

1. Open the sandbox where your group has been drafting in Edit mode. (References and other templates will break if you copy from Read mode.)
2. Select the portion you want to move into the live article.
3. Open the original article in Edit mode and add your content into the article.
4. Add an edit summary that says it copied from your group's sandbox, and click 'Publish changes'. (Include a link to that sandbox, like [[User:Your Username/sandbox]], in the edit summary.)
5. Repeat this process for any other parts of the article you worked on.
6. Make sure that the lead section reflects the new content you've added. And copy-edit the article to ensure your additions mesh well with the preexisting content.

Once you've gotten the hang of it, you can make additional changes directly in the article, or repeat the sandbox procedure each time you add new content.
