There are some great information on this forum that seems to be available publicly (I can access it in an incognito chrome window) and I would like to increase the chances of this information surviving for a long time.
When I try saving a EA forum page it looks like it does not render correctly on the wayback machine. Ex: https://web.archive.org/web/20200624163706/https://forum.effectivealtruism.org/posts/8vfadjWWMDaZsqghq/long-term-investment-fund-at-founders-pledge
The https://lesswrong.com website seems to have the same issue .
I opened a github issue on LW's repo since I assume it is an issue with the source code of LW.
