Occasionally, when I find myself working on a particularly lengthy answer, I'll want to share my answer with a friend or college to ask questions or receive feedback before posting. My typical workaround is to post answers I want to share in the formatting sandbox if they aren't ready for submssion.
I don't enjoy this solution, as it feels like an unintended use of the sandbox. It bumps the formatting sandbox to Meta's front page, is only possible for users with 10+ rep, and crowds more answers onto a post that, according to Shog9, was already overflowing with 900+ answers before it was wiped clean and archived.
Is there a better way to share unfinished questions or answers before posting?
