Guillaume-
I didn't speak about submit whatever people want, but just propose alternative logo based on elected concept.
You're free to propose whatever you want. You're just not free to add it to the final ballot. That's the artists' decision.
I just regret that the rules was not cleary defined before vote start
That's simply not true. The voting rules have all been on [[International logo vote]] before the vote started. I have been careful not to change any rules during voting.
I don't specially like to be treat as lier especially when I'm not ;o) When the vote begun, the rules of the second round didn't allowed variants. This (good) rule was add by you the 6th of september at 12:55 (to be precise).
That's incorrect. I made clear before the first voting round on the vote page that variants would be voted upon in the final stage ("What about variants? ... In the second [now third] voting stage, you will have an opportunity to grade each logo variant individually." That part was written together with the other rules on Aug 27, right before the vote started.) I just clarified the number of variants after the first round closed and before the second one began. This was not a change of rules during voting.
Regards,
Erik
