Just as a friendly reminder since people have expressed that they didn't know this existed before and the chatbox has been getting a lot of activity of late... to view more than just the most recent chatbox archives there's a link at the top of the chatbox that you can click. It looks like this: Wyvern Chatbox [Archives
]. Click on archives and you'll be taken to a page where you can scroll through all he messages ever. By default you're shown all the chat messages from the last 24 hours. To look beyond that scroll to the bottom, click on the drop down menu that with "Yesterday" displayed, change the period of time you'd like to view, and click go.
