Where to start!
Add or update content
Make sure content is on the "right" page and is not duplicated or out of sync with related content. Domain members are initially responsible for contributing, categorizing and populating the BOK with content. Domain editors will validate other domain member contributions.
Explain your edit
Make comments on your edits and keep them friendly. These comments will help others understand the changes and may improve the content further through shared understanding. Before making significant changes to content, discuss with the contributor. Consider using the Sandbox to demonstrate your change. Whenever possible, avoid overt opinions and work in a way that will avoid reverting pages. Be inclusive, not exclusive.
Minor edits to existing pages, such as formatting changes, grammatical improvement and uncontentious clarification, may be made at any time. Discuss and publicize major policy or guideline changes to the contributor and the domain members.
Working with the TCBOK is about collaboration, community and creativity. All contributors are responsible for a dialogue and negotiated meaning. Deleting is a major source of contention and discomfort; refactoring and polite editing are preferred. Negotiate to yes for a "sign-off" on all large changes.
Fix problems if you can; flag or remove them if you can't. Preserve as much content as is reasonable. As long as any of the facts or ideas added to the article would belong in a "finished" article, they should be retained and cleaned up on the spot. If you think a page needs to be rewritten or changed substantially, go ahead and do it, but preserve any content you think might have some discussion value and comment in detail about why you made the change. Improve poorly presented content by rewriting the passage. The editing goal is to guide articles through higher levels of quality and this can take time.
