Let me start by saying that I am not sure if I am posting this in the correct board, however this purpose of me making this thread is to help users obtain meshes from websites that may no longer exist.
First things first is go go to this website:
https://web.archive.org/This website provides and explanation of what it does on the site, but TL;DR - it will allow you to search for logged pages in internet history.
so for instance if you enter Burnsight's website url, which held many very lovely WOW meshes that are now no longer available due to the website's url no longer being maintained, you can now access the pages that hold those urls/downloads!
Voila!! <3
Hoped this helped some people complete some tiresome searches. c:
