CHANGE: Various moderator email and push notification cleanups.
NEW: When viewing a database table, pin the header at the top of the page.
BUGFIX: When deleting a database row from the /table view, we did not log that in the activity log.
NEW: New Moderator Notifications for changes to Chats/Photos/Files/Wikis/Databases. Currently in testing.
Note: I will be on vacation next week, although I plan on enabling the new moderator notifications for everyone on Monday if there are no issues found during testing over the weekend.
