Would there be any objection to setting up a daily-image-l mailing
list akin to English Wikipedia's daily-article-l, but for featured
pictures from Commons?
Of course, for bandwidth reasons, we would only link to the image,
instead of emailing it to each subscriber :) with brief multilingual
labels and copyright credit.
[[m:Mailing list]] just says to contact a dev to start a new list, but
I imagine they like to know that the idea has been run past other
people first. :)
