For years, Pete would occasionally add extra information linked to a particular strip, such as sketches or the story behind the joke. Defenders of the Nifty would see these as small shields beside the strip, and could read the Compendium info in the archives.
Then this function broke on the site, and Pete could not add any more little shields. The dark ages of no behind-the-scenes Sluggy snippets began.
With the new site, all the past Compendium info is there for Defenders to see, and Pete can finally add new entries in the future!
