This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
I downvoted because, although you did answer the question, I thought the first half of your response was unnecessary snark -- making it sound like you'd prefer the questioner leave the site -- in response to a reasonable question about a feature that many sites do have. (Especially since it's a stupid questions thread.)
Thanks for explaining your downvote. I was not, as it happens, recommending that the questioner leave the site, nor expressing a preference that s/he do so. I just thought it was funny. The possibility of that misinterpretation did occur to me, but I didn't find it serious enough to worry about. Perhaps I was wrong; in any case, if WhyAsk happens to be reading this and took me to be saying "go away", I hope s/he will accept my apologies.
[EDITED to add: It looks like my comment is on +5-3, which suggests that probably at least two other people took it as hostile snarking. Oh well.]
