Encountered A Dead Link?

Don't worry, I saved most linked pages on the Internet Archive. If you still encounter a dead link, then right-click the dead link, copy the link address and paste it in the Wayback Machine to find its archived version. Always select the most recent version date at the top of that Internet Archive page. If you did find a dead link in this blog, let me know and I will fix it. My goal is to preserve all relevant information.
