I posted a "proposed update" to the mortgage tag wiki yesterday, and got a message that it would display after being peer reviewed.
I've also noticed that I have the approve tag wiki edits privilege, but I have no idea how to use it.
How does this feature work?
This Meta SO question is similar to mine. It explains the mechanics, but it doesn't address the tag-wiki piece well. ("How can I see proposed edits on a site-wide basis?")
(It also isn't clear if this is fully implemented for this site -- this is a new feature.)
See this SO blog post for background.
Edit: I see them showing up now -- a "1" with a circle around it next to the "tools" link in the toolbar.
