The Genesis3D 1.x forum is back and live at https://www.genesis3d.com/archive for historical purposes.
It's a completely separate database so your username / password *here* won't work *there* unless you re-register. If you had an old username over there, that one exists so the posts have users attached to them but the passwords couldn't be brought over so you'll have to go through the password recovery system to get it back. Hopefully you still have the same email address from 10-20 years ago!
And now this database is taking back it's spot at /forum, which should make rtxA happy.
