The trend of having a question "sandbox" on a per-site meta so that users new to the site (or not) can post a draft of their intended question as an answer, and have it reviewed by site regulars before they go on to actually post the question on the main site, has gained a lot of traction on many sites. On Interpersonal Skills' version (don't know about other sites), people posting to the sandbox are expected to indicate the intended title and tags of their question as part of their sandbox submission. I only figured this out because there was an existing answer that contained them; if it wasn't there, I wouldn't have known. (The site requires that sandbox drafts which go on to be posted as questions be deleted.)
I propose that we add a new moderator-only tag question-sandbox, which would indicate that the question is one set aside specifically for that purpose, which would prefill the answer form with a template that can be useful for prompting users to add in the required title and tags, and create a unified and consistent theme for the submissions, such as:
### [draft title] **tags:** [tag:tag1], [tag:tag2], [add more if needed] --- [Your draft question body here]
We already have a tag with similar functionality, community-ads, which prefills the answer form with the template for posting Community Promotion Ads.
This is also a first step towards allowing users without the necessary 5 rep to use the sandbox, as one can use the presence of this tag to allow users without the required privileges to answer it. (The tag above also has a special feature attached to it; it causes answers above certain score to be parsed and displayed as ads.)
