UESP Forums

here and there in the wiki and in old places in this forum, I see items like "this was discussed in the <official/other/something> Elder Scrolls forums". Wondering what other forums there are/were (besides the big-business stuff like reddit/facebook/discord). Maybe there's some snapshots on the Internet Archive if I know what to search for.

So far I've found:
https://forums.elderscrollsonline.com/
forums.bethsoft.com archived by the Internet Archive

I remember spending a lot of time on the old Bethsoft forums before they were shut down. A lot of smaller Elder Scrolls communities existed too, but many have vanished, so the Internet Archive fnaf is probably your best bet for finding them today.

There was also The Imperial Library, Chorrol.com, Emma's Elder Scrolls Forum, and any number of modding-related forums (Planet Elder Scrolls, TES Nexus, Tamriel Rebuilt, Silgrad Tower, etc).
