These are some things you can do to improve the quality of Wikipedia coverage of Christianity.

1. Interact with from editors interested in Christianity and Christianity-related topics.
2. Look over the recent changes list for recent improvements to articles, other changes, and vandalism.
3. Create collaborative projects to systematically improve coverage.
   • Possibly including:
   1. A regular collaboration.
   2. Adopted Topic, where a suite of topically related articles are targeted for improvement until there's a consensus to move on to a new topic. (see here)
   3. Article Review, for articles nominated by members for wider review. In this case the new ones go at the top and sink as new ones are added. (see here)
   4. Bring a more neutral voice to articles which categorize a movement as non-Christian or a cult.
4. Improve the WPChristianity banner that goes at the head of Talk Pages to handle tags for unreferenced, copyedit needed, cleanup needed, expansion needed, and POV warning.
5. Add more reward templates or barnstars (extant awards can be found here, and have people in the task force actually watching logs and rewarding key contributors.
