Caching

AMO uses Zeus, which heavily caches content

If you see some_string_define on AMO, it's either 1) a raw string define, or (more likely) 2) Apache needs to restart to pick up the gettext() changes

To view the revision of AMO you're currently seeing, view-source of any page; in the bottom, you'll see something like [pre ]; this means you're at SVN revision number 24322 -- you can cross-link this to whatever revision number was posted in the checkin comment in the bug.
