Post a single word comment in the discussion to cast your vote.
yes / oui / ja / si / sim -|- no / non / nein / nao / nee
A comment marked as edited by the system, will not be counted, so as to rule out the suspicion of tampering. To correct a mistake, you have to delete the post, and add a new comment.
Do not post a second vote, only the first will be counted, so you will not be penalised for an honest mistake.
