Or simply to randomise it entirely. If either of those aren't possible for technical reasons, it might be practical to rotate them - run each button for x many hours at a stretch, rotating them so as to ensure they don't regularly go up at the same time (of the day or of the week) and so that they get roughly equal coverage. -- - Andrew Gray andrew.g...@dunelm.org.uk _______________________________________________ foundation-l mailing list foundation-l@lists.wikimedia.org Unsubscribe: https://lists.wikimedia.org/mailman/listinfo/foundation-l
