I don't do 3D modeling very often, but when I do, I always use Anim8or. Sometimes I come here to read if I need help remembering how to do something. Due to forum registrations being closed at the moment, that is the biggest hindrance for would-be new users to start some fresh discussion or introductions. However, I understand they've been locked down for a bit due to high volumes of spam.
I was able to create this account by contacting Steve, but I think many (possibly younger) newcomers will not want to go through the effort of registering an account here when they can join a Discord server. This is no fault of the forum, but a side effect of the Internet's current state of affairs. Stepping away from forums as a whole - or any sort of discussion boards where guests can read without requiring an account - restricts information from being easily accessed, disseminated, or archived. It's concerning for the long-term health of the Internet, especially when you factor in that a Discord server (which are either seldomly archived or difficult to) can be closed or deleted at any time. That means hundreds upon thousands of messages and files can be made inaccessible or lost in an instant. At least with Wayback Machine or other archival sites, you can view past pages here or save copies if need be. A lot of people learn by simply lurking and reading. When you answer a question here, you aren't just answering one person, but countless silent readers that wondered the same thing. If people want to use Discord or similar messaging apps, that's their choice... but I'd highly recommend archiving things on there if you value them!
Occasionally I have come across people discussing their distaste with Discord and wanting to move back to forums, so perhaps old things are becoming new again. I'm sure we'll be back in style before you know it.
