This idea is somewhat borrowed from puzzling.se's Riddle Sandbox and math.se's Draft Sandbox threads.
Would it be helpful or beneficial to have a thread on meta for posting question drafts as answers to receive help getting them stack shape before posting them on main?
Right now, when I want to trial a question before posting, I can only briefly describe my question in chat and then get some brief thoughts from those present. I would love to be able to format my full question as an answer here on meta and allow the community to leave comments and make edits as we work together toward a good question for main.
I think there are also some potential benefits for newer users here - it gives us a reason, and them an incentive to visit meta. It could be an opportunity to point newer users toward a place they can workshop their questions into good shape for the main site. I know we already try to do this on main, but getting users familiar with meta is a good thing, and this could be a good opportunity for that.
