@stumblebee No problem! What I meant to say is that I would dearly like to alter that page to strongly suggest that a downvote should have a suitable comment attached to the relevant answer or question but elected Mods cannot actually edit that page.

Interestingly enough this is not addressed here: askubuntu.com/help/privileges/vote-down And unfortunately this page cannot be edited by elected Mods...

I have made the changes above...

Not sure if any more Community input will be forthcoming, we should proceed I suspect...

@Levente I see that the wallpaper tag has this description in the 'Usage guidance (excerpt)': 'For questions regarding the image displayed on the desktop background. ' It would be a fudge but perhaps this could be extended a little: 'For questions regarding the image or solid colour displayed on the desktop background. ' This could be explained further in the currently non-existent full tag wiki...

Perhaps a week (from the time of posting of this question) is enough time to allow for comment before making the more definitive changes?

I have joined in moving relevant tags from background to background-process. Looks complete now?

Terdon, as always, has presented a great answer for you. Could I suggest as well that if you are interested in culling disinformation on Ask Ubuntu specifically: assemble yourself some more rep points and join the chat site that covers many editing issues on Ask Ubuntu: chat.stackexchange.com/rooms/3877/raiders-of-the-lost-downbo‌​at

This has been pushed vigorously by Stack Exchange, Inc. and almost always vigorously resisted by the Community. My personal preference is not to opt in...
