Also, if it is a tiny bit helpful, I have all of my posts saved on my computer and my CS's. I didn't save anything else though. (I totally missed the beginning of the latest chapter too so I don't know what's going on)
Your best bet is to use Google, type "site:roleplayerguild.com" plus the title of whatever threads you were in. Example: "site:roleplayerguild.com kill sacrifice of flesh" This will give you all the listings Google finds. Next to each listing is green arrow pointed down. Click on this. It will give you the option for 'Cached' or 'Share'. Click 'Cached'. This will bring up an archived version of the page. The links on this page will not work as they will try to bring you to the old site; you must do this page by page. Not all posts were captured. This does not work with PMs.
