The OpenSCAD Mailing-list is a place to discuss usage, problems and development topics related to OpenSCAD.
If you wish to join the discussion you can either send an email to email@example.com (no subject or content required) or manually, see below under Membership.
You will receive a confirmation email which you must reply to, check your spam folders.
The Mailing-list Archive has a Web front-end at https://lists.openscad.org/empathy/list/discuss.lists.openscad.org which is provided by the list hosting company, but it's not a Forum and has a number of bugs & it is not recommended. Particularly not for Posting New Threads.
It may be useful for searches, but topics displayed are badly formatted. Of note it can 'format' .scad code, introducing errors.
NOTE: The old Nabble hosted Web based Forum at forum.openscad.org remains as the read-only archive now.
