I know this is a pretty smart crowd over here, but I didn't know this until just recently, so I'm sharing it here with you: If you come across a gem of a website that you fear might get taken down soon, yes, go ahead and archive it to archive.org or the waybackmachine. But I found something else you can do too. Scroll all the way from top to the bottom of the website to make sure that everything gets uploaded and refreshed, then right-click on the page and click print (or just hit print screen on your keyboard). Know you're given the option to save as a pdf. Now you've got your own personal backup of that webpage that you can print out on paper at anytime you want or copy onto a thumb drive for easy access and portability. Even though archive.org is supposed to be like a digital ark or sanctuary for wayward webpages, you're still uploading that webpage to someones very hackable server farm somewhere. It's a lot more difficult for them to come thru a backdoor to your computer (or your house lol) and error 404 your thumb drive or your physical print out. I think we should all start adopting this practice in retrospect and from here on out. Internet Download Manager is also a supremely amazing program to have installed, it allows you to very easily download any video, music file, pdf, or anything from any website, in just 1 click. I've been using it for years to download every video I ever watch.
