For those that don't know, a Sandbox is a meta question that is constantly maintained as a place for users to get feedback on their questions before they post to main. Users can post their questions as answers to the Sandbox meta question and receive feedback from the community for how they could change to be better received.
For more, you can see the working Sandbox over on Worldbuilding where they explain it much better than I could. They even have new Sandbox answers post directly into their chat!
We had an interesting discussion a while ago on whether or not we should open a Sandbox. The top answer there gives a good walk-through of what we'll need if we do decide to have one. The answer ends with:
If people are willing to work at these, then I'd agree with this. But we need to keep in mind what this will require.
I for one, would love a Sandbox and would be happy to help maintain it. What can I (an average Joe user) do to push for its creation and show my support? I've upvoted the linked question and it's answers but the post is from almost a year ago and nothing has come of it.
What can we do to kickstart the creation of a Sandbox?
