Please do not move or completely change articles. Instead add a Cataclysm section (==In Cataclysm==) with the information of what will change; also use {{Cata-section}}.
For major new articles about Cataclysm subjects, please place {{Cataclysm}} at the top.
Please replace me with an appropriate stub from Category:Stubs after the expansion is released.
{{Cataclysm/Update}} - Should only be placed on existing articles that are known to dramatically change
This article or section is likely to dramatically change once the Cataclysm begins.
Feel free to update any incorrect values (e.g. ability and talent articles), but please avoid overwriting all previous information with more current information (e.g. location and NPC articles).
What should I do to an article containing a subject that no longer exists?
Add the {{Removedwithcataclysm}} tag to the top of the article and (if it's a gameplay-focused article) remove all other categories. You may have to place |doc= into certain templates to prevent the auto-category from them.
What if just a section in the article no longer exists?
In this case you'll just need to add {{Rfg-section}} to the section and add a ==Patch changes== section with the relevant changes towards the bottom of the page.
What if I come across an article that doesn't exist for something added in Cataclysm?
Create the article like normal, but also add a ==Patch changes== section with {{Patch 4.0.3|note=Added.}}.
What about zones and subzones? Those articles are usually big and contain cited information, can I remove the information if it no longer applies?
No, that information should be kept for historical reasons. For now you can add a ==Cataclysm== section and note the changes to the zone or subzone. The infobox, however, should not be touched for the most part. In a few cases certain zones may be moved to be preserved and then replaced with more current information, this should be decided by either a vote or some other means.
What templates should I use for new or even existing Cataclysm articles?
I just saw an image on an article that is wrong (but the name is correct) or needs updating, how can I easily do that?
Thanks for asking... it's actually quite simple to replace an out of date image. Just click on the image in question, use the bottom right icon on the lightbox to visit the file description page, scroll down to below the file history and look for a link that reads Upload a new version of this file. Click on that, then upload like normal.
If you upload a new image under a different name, but as to replace a current lesser quality file, please remember to add the {{speedydelete}} tag to the old image.
When can I remove the Cataclysm stubs/tags from the top of articles?
When the article is completed or mostly completed, you can replace the Cataclysm stubs with its appropriate stub type (ie: location, item, NPC, etc). See WW:STUB for the full listing.
I have an issue and need help, but this guide doesn't answer my question... who will?
You can ask a currently active admin or an experienced user on their talk page. You could also join the WoWWiki:IRC and ask your question there. And if all else fails, you can create a new forum topic and ask there. (Please don't post your questions here.)
