I've just come across a question from someone clearly inexperienced with electronics trying to build a potentially dangerous AC/DC rectifier. An expert gave a very precise answer, but there was no mention of safety issues the OP may need to address to accomplish his task safely. But we newbies just don't know we don't know important stuff.
So, my question is, should we take advantage of those opportunities and warn inexperienced users of potential safety issues? To make the task easier, we could create a few safety boilerplate questions and answers and provide links to those. What's the EE.SE policy on the issue?
