This is actually a task for sorting through a small list of seemingly
easy things. Many of the items here are probably within the grasp of
an interested admin to just fix rather than waiting on us for.

Brandon is planning to sweep through on all of these and come up with
a few specific recommendations. If you have some thoughts, we'd
appreciate them here.

4a. Better links to documentation on PC related specialpages - from
the comments: "The review page could have links to Help documentation,
reviewer guidelines, and PC policy pages."

4b. Incorporate the PC protection rationale (protection log message)
into the review screen as instruction to the reviewer - from the
comments: "Make the protection rationale visible (currently it's
click-to-expand). That way Reviewers could see up front if PC was in
use for Vandalism, BLP, edit warring, etc. Helps alert them to the
'type' of problematic edits, particularly more subtle kinds."

4c. Add short reviewer instructions to the review page - from the comments: "
Just a summary of how to review. Depends on policy discussions about
reverting vandalism or also poor edits. Currently could just include
the reviewer guidelines writ small.

4d. Quick link to Pending Changes specialpages - from the comments:
"Easy access from the sidebar, or other common locations (not sure
where)."

Obsolete.
