I just ran across this deleted answer, which missed the fact that the question was specifically about halachah on Shabbat.
I don't feel that the appropriate response was to delete this answer, just for missing the halachic question involved. The answer had at least some shaychus to the question, so the appropriate thing to do here is let the readers vote it down.
I can't even vote to undelete this answer since it was deleted by the moderators. Could you moderators be careful to apply your moderation superpowers sparingly?
