Yeah, the 'cache' fuction is what I was thinking of. However, using the 'site:roleplayerguild.com <insert whatever you're searching for here>' only seems to yield results from this site rather than the old one, even though it definitely used to give results from oldguild. Am I just bad at searching for the right key terms?

I hadn't realised stuff from oldguild was on the Wayback Machine, but that doesn't seem all that useful seeing as it doesn't have threads archived.
