In order to make the Sandbox easier to use, a new Sandbox question will be posted when the old one becomes too full. This Sandbox is currently active. You can check here for the full list of past and present Question Sandboxes.
What is the Sandbox?
This "Sandbox" is a place where Worldbuilding.SE users can get feedback on prospective questions they wish to post. This is useful because writing a clear and fully specified question on the first try can be difficult. There is a much better chance of your question being well received if you post it in the Sandbox first.
To post a question to the Sandbox: Post an answer to this post with the content of your proposed question. You can create as many answers as you have proposed questions, but it is recommended that you only work on one question at a time. The content of the post should be as close as possible to the format you would use when asking on the main site. If you would like, you may add a section at the bottom explaining what parts of the proposed question you are most worried about (See the Sandbox FAQ for more information on suggested syntax).
Once you have posted your proposed question, users will be able to comment on it with feedback. You can then respond to their feedback with comments of your own, or make edits to your post to attempt to address their feedback (after editing, be sure to comment to notify the user that you have taken their advice). The feedback/edit cycle can go on for as long as needed until either you are confident that your question is ready to be asked on the main site, or you've decided the question just won't work.
When you think your question is ready for the public, go ahead and post it to the main site. To help keep this sandbox clean, you should edit your post here so that it contains the title and URL of the posted question, and nothing else. Regardless of whether or not you decided to post to the main site, once you are done with your Sandbox post, you should delete it. This will not completely delete the post, but it will get it out of the way so that new proposed questions can be more easily located.
Keep the Sandbox clean. In order to keep the Sandbox clean users are encouraged to look out for questions that have not seen any activity in some time. If you come across a question draft that has not seen any activity from the author in the form of edits to the draft and comments as responses to other peoples comments you should leave a comment. In the comment you should ask if the user is still working on the question draft and remind him that his post might be deleted in the future if there is no further activity. If you see a question draft that has not seen any activity for at least 30 days and that has had a comment asking if the author is still working on the question draft for at least a week you should flag the post for moderator attention and ask for deletion. This helps to keep the Sandbox clean in cases where the author has abandoned his question draft.
Delete your comments when they no longer apply. It's normal that the OP will incorporate the feedback they get into their posts. Please make it easy for others to see which comments are still relevant to the discussion by removing your obsolete ones. In addition you can ask a mod to purge comments under graduated posts or move them to chat under abandoned posts to make it easier for users that can see deleted posts to use the Sandbox.
Use votes sparingly. Up- and Downvotes in the Sandbox should be used sparingly as the drafts here are supposed to be questions that would not fit the guidelines of the Main site in their current form. Only upvote if you think a draft is ready for the Main site and only downvote if you think that a question is just not a good fit, no matter how much the OP works on the draft. In any case, please write a comment to explain your voting. We don't want to unnecessarily discourage the OP, but we also don't want them to waste their time.
Please avoid answering questions here. I know it's tempting, but answering the question in a comment will clog the comments and make it harder to see good guidance. If you have an answer for the proposed question, simply wait for it to be posted to the main site, and answer it there.
See the Sandbox FAQ for more information on how to use the Sandbox.
Please make sure you wait at least a day after posting into the Sandbox to give a range of people time to see the question and respond.
